An exponent is also known as a superscript in word processing.
When working on a scientific or a mathematical document, look for theSuperscriptfeature in the word processor.
Microsoft Word, Pages in macOS, and presentation software like PowerPoint and Keynote have the superscript format.

But you may have to rely on another workaround if your keyboard doesn’t have a numeric keypad.
Select and hold theAltkey on the numeric keypad.
throw in the alt code (0185) in sequence for exponent one using the numeric keypad.

Similarly, useAlt+0178for exponent two andAlt+0179for exponent three.
Use the Character Map to copy and paste superscript numbers for exponential calculations.
In theSearchbar, enter “character map”.

snag the result to bring up the Character Map.
Scroll through the little tiles or enter “superscript” in the Search field to display the superscript available.
If you don’t see the Search field, selectAdvanced viewto reveal more menu options.

go for the superscript number and use theSelectbutton to make it appear in theCharacters to copyfield.
SelectCopyand then paste it in the program you need it in.
For instance, X2.

pick the number you want to raise as an exponent.
SelectFormat>Font>Baseline>Superscript.
Unlike the iOS keyboard, the function is built into the numeric keys.

grab the?123keys to shift to the number keypad.
pop in the base number or a variable like “x”.
Press and hold on the number you want to select for the exponent.
grab the superscript from the options that appear above the number.
you might use Text Replacement for occasional uses.
OpenSettings>General>Keyboard>Text Replacement.
Select + in the top right corner.
Go to a symbol generator website and create a superscript for the desired number.
UnderPhrase, paste the number which will act as the exponent.
UnderShortcut, enter a shortcut (like “^2”).
Use the shortcut in any text and repeat the steps to enter text replacements for other exponents.
If you’re using Word Online, highlight your text and select thethree dots>Superscript.
