Exponents are smaller, raised text that signify multiples of a base number or variable. As an example, "X" with a smaller "2" raised just afterward signifies "X squared," or X multiplied by X. Exponents are difficult to display in simple text, but Microsoft Word's advanced fontformatting features allow you to add raised exponents to display them properly.

Type the text to be displayed in Microsoft Word. To write "X squared," for example, start by simply typing "X2."

Use your mouse pointer to highlight the portion of text that should be raised as an exponent. In the example, highlight the "2" in "X2."

Click the exponent button, located in the "Font" group of the "Home" tab. This icon displays X with an exponent of 2. The highlighted "2" will become smaller and be raised slightly above the "X."
Tips & Warnings
 Exponents are not restricted to mathematical expressions. You can also use raised text to signify citations or additional notes in a Word document.
