Ideally using a superscript 4 to the right of the thing being raised to the power of 4. Computer languages can use: 1) a double multiplication sign - a double asterisk, eg 2**4 is 2 to the power 4, which is 16; or 2) the caret symbol, eg 2^4 is 2 to the power 4. The latter (using the caret symbol) is often used when a superscript is impossible, outside computer languages.
2 to the power of 8.

As a to the power of 2 is the same as a squared then how about this a2
2 to the power of 8.

2^20
Example: 1/2
2 to the power of 20 is written as: 220
( 24)2
Write the number 2 in superscript (that is, a small number to the upper right). If you're trying to do it by computer and you don't have the option to use superscript, the standard is to put a caret and then a 2. Here's an example of how to write 5 squared: 5^2 Incidentally, this is the same way you write a number to any other power.
