The Fastest Method: The Superscript Keyboard Shortcut
Superscript is the formatting Google Docs uses for exponents. It raises the selected characters above the baseline and reduces their size, which turns 10 3 into 10³. The keyboard shortcut applies that formatting without opening a single menu, which makes it the first method worth learning for anyone who works with powers regularly.
Type the base, for example x or 10.
Press Ctrl + . (period) on Windows and ChromeOS, or Cmd + . on a Mac.
Type the exponent. The cursor now writes in superscript.
Press the same shortcut again to switch back to regular text.
The shortcut works as a toggle, so the same keys turn superscript on and off. It also works on text that already exists. Selecting the 2 in x2 and pressing the shortcut raises it in place, which is the fastest way to fix a document where powers were typed on the line, such as m2 instead of m².
Negative and multi-character exponents follow the same pattern. Typing 10, switching to superscript and entering -6 produces 10⁻⁶, and an expression such as 2ⁿ⁺¹ only needs n+1 typed while superscript is active. When the question is how to do powers in Google Docs, as with squares, cubes or powers of ten, this shortcut answers it in under a second.
Adding Exponents Through the Format Menu
The Format menu applies the same superscript formatting with the mouse. It suits occasional use, touchpads and keyboards where the shortcut does not respond.
Highlight the character that should become the exponent.
Open Format > Text > Superscript.
Place the cursor after the exponent and repeat the path, or press the shortcut, to continue in normal text.
The menu lists the keyboard shortcut next to the Superscript label, which makes it a handy reminder while the keys are still new. Subscript sits directly below it, ready for chemical formulas such as H₂O or indexed variables such as x₁.
Writing Formulas With the Equation Editor
Superscript formatting is ideal for a single power inside a sentence. Longer expressions, such as fractions with exponents or polynomial equations, are easier to build in the equation editor, which keeps every part of the formula aligned.
Open Insert > Equation. An equation box appears in the text, and an equation toolbar opens below the main toolbar.
Type the base inside the box.
Type ^ to start an exponent, or pick the x^b option from the Math operations menu.
Type the exponent, then press the right arrow key to return to the baseline.
The editor also accepts shortcuts for common symbols. Typing \times followed by a space inserts a multiplication sign, the standard way to write scientific notation such as 6.02 × 10²³. The underscore starts a subscript in the same way the caret starts a superscript. In nested expressions, each new caret moves one level higher, and the right arrow steps back down one level at a time.
Equations look cleaner in worksheets and lab reports, but they behave differently from normal text. They ignore the regular font menu and can break when copied into other apps. Checking the math itself is a separate task. Confirming that an exponent rule was applied correctly before it goes into the document is something a reasoning model like DeepSeek can work through step by step.
Inserting Superscript Characters From Special Characters
Google Docs also includes ready-made superscript characters: ⁰ ¹ ² ³ ⁴ ⁵ ⁶ ⁷ ⁸ ⁹, along with ⁺, ⁻, ⁼, ⁽, ⁾ and letters such as ⁿ and ⁱ. These are separate characters rather than formatted text, and that difference matters more than it first appears.
Open Insert > Special characters.
Type superscript in the search box.
Click a character to insert it at the cursor.
Superscript formatting disappears when text is pasted into a plain text field, such as a Google Form, a chat message, a spreadsheet cell or a social media post. In those places x² silently becomes x2. A true superscript character survives the paste because it is part of the text itself, so special characters are the safer choice for anything that will leave Google Docs.
The trade-off is coverage. Every digit has a superscript version, but only some letters do. That makes these characters a better fit for units and simple powers than for algebra with many variables.
Creating Automatic Exponents With Substitutions
Documents that repeat the same notation, such as m² and cm³ in a science report or 10⁶ in a finance summary, can let Google Docs insert exponents automatically. Automatic substitution replaces a typed sequence with another character as soon as a space or punctuation mark follows it.
Open Tools > Preferences and select the Substitutions tab.
Make sure Automatic substitution is checked.
In the Replace field, enter a sequence that never appears in normal writing, such as ^2.
In the With field, paste the ² character copied from Special characters.
Click OK.
From then on, typing m^2 followed by a space produces m². The same setup works for ^3 or any other frequent power. Substitutions belong to the Google account rather than to a single file, so they apply in every document. Few guides mention this method, yet for repetitive notation it is faster than any shortcut.
How to Write Exponents in the Google Docs Mobile App
The Google Docs app on phones and tablets has no keyboard shortcuts, but superscript sits in the text formatting panel on both Android and iOS.
Android
Open the document and tap the pencil icon to start editing.
Type the base and the exponent, then double tap the exponent to select it.
Tap the Format icon (the A with lines) at the top of the screen.
In the Text tab, tap the superscript button.
iPhone and iPad
Open the document and tap the pencil icon.
Select the character that should become the exponent.
Tap the Format icon (A) at the top.
In the Text tab, tap the superscript button.
On both platforms, the same button turns superscript off again. Documents with many formulas are still easier to finish on a computer, because the mobile app does not offer the full equation editor.
Google Docs Exponent Shortcuts on Mac and Windows
The keys are the same on both systems apart from Ctrl and Cmd. Superscript is Ctrl + . on Windows and ChromeOS or Cmd + . on a Mac, and subscript uses the comma instead: Ctrl + , or Cmd + ,. Ctrl + \ (Cmd + \ on a Mac) clears formatting and resets the selection to the document's default style, a quick way to remove stuck superscript from a longer passage. Ctrl + Alt + F (Cmd + Option + F on a Mac) inserts a footnote, and Google Docs formats footnote numbers as superscript automatically, so there is no need to raise them by hand.
Which Method Fits Each Situation
The right method depends on what the exponent is for and where the text will end up.
Homework and class notes: the keyboard shortcut is the fastest way to add squares, cubes and powers of ten inside sentences. Worksheets built around full equations look tidier with the equation editor.
Scientific notation: the coefficient, the multiplication sign and the base stay on the line, and only the power is raised, as in 3.0 × 10⁸ m/s.
Units of measurement: m², cm³ and km² repeat often in reports, which makes automatic substitutions the most efficient choice.
Chemistry: ion charges such as Ca²⁺ and SO₄²⁻ use superscript, while atom counts like the 2 in H₂O use subscript. Mixing the two is one of the most common errors in chemistry write-ups.
Text that leaves Google Docs: forms, emails, spreadsheets and social posts need special characters, because formatting does not survive a plain text paste.

Fixing Common Exponent Problems
Most exponent issues come from formatting that stays switched on, or from shortcuts that never reach Google Docs.
The shortcut does nothing. Browser extensions and some keyboard layouts claim Ctrl + . for their own actions. Format > Text > Superscript works regardless, and testing the shortcut in an incognito window or another browser usually reveals the conflict.
Everything after the exponent stays small. Superscript remains active until it is switched off. Pressing the shortcut again before typing, or selecting the affected text and pressing Ctrl + \ (Cmd + \ on a Mac), returns it to normal.
The exponent disappears after copying. The destination accepts plain text only. Superscript characters from Special characters keep their position in any app.
The exponent is hard to read. Superscript scales with the surrounding font size. A larger font for the line, or an equation for display formulas, improves readability in slides and printouts.
The numbers need to be calculated, not just displayed. Google Docs formats numbers but does not compute them. In Google Sheets, =2^10 or =POWER(2,10) returns 1024, and the result can then be copied into the document.
Writing and Checking Math Notes With Chat & Ask AI
Formatting an exponent takes one shortcut, but explaining the math around it usually takes longer. Chat & Ask AI handles that part. A student can paste a problem such as "simplify (2x³)²" and receive a step-by-step solution, while a teacher can request ten practice questions on exponent rules with an answer key, ready to paste into Google Docs and format with superscript.
The AI Writer turns rough notes into clear explanations, lab report sections or study guides before any formatting begins. Models such as Gemini, familiar to many Google Docs users, sit in the same app alongside other leading models, so an important answer can be checked against a second model in seconds.
