If you are using Microsoft Word it is very easy.

Luckily there are usually specific ways to write a superscript in most desktop publishers. Not only can it make you look unprofessional and untidy but it can also be misleading and highly significant to the meaning of the writing. It can often be frustrating when you want to type a superscript such as 'x2” into a word processor and it comes out as x2 or x2. In this case you want to write a number that represents the second power, such as x2. Subscripts and superscripts are perhaps best known for their use in formulae, mathematical expressions, and descriptions of chemical compounds. It often depends on type of word processor or publisher being used but most versions have the compatibility to type a number as a superscript such as 'x2”.Ī subscript or superscript is a number, figure, symbol or indicator that appears smaller than the normal line of type and is set slightly below or above it - subscripts appear at or below the line while superscripts are above.
