How do you do SX on a calculator?

To do SX on a calculator, you will need to use the exponential function (usually denoted by the letter «E» or an exponent symbol). The exponential function takes the form of E^x, where «x» is the number you are raising to the power of an exponent. For example, to calculate 5 to the power of 3, you would enter «E^3» into your calculator, and the result will be 5^3 (or 125).
