Write the exponent with superscript. Superscript is a form of type or writing where the number in superscript is slightly smaller and raised higher than the rest of the text. The normal text is the base number, or the number that gets multiplied by itself, and the superscript is the exponent, or the number of times the base is multiplied by itself. The superscript number follows the base number.
Notate the exponent with a carat, which is the symbol "^." Write your base number first, followed immediately by the carat, then immediately follow the carat with the exponent. An example: 5^6, where five is the base and six is the exponent.
Write the exponential form with words. For example, instead of "5^6" you could write out, "five to the sixth power" or "five to the power of six."
