Every calculator is a little different in terms of the order in which you're expected to press the buttons. For a graphing calculator, there is a ^ button that represents how you would type something in as an exponent. On a scientific calculator, there is usually a button that says "x ^ y" or "y ^ x" that you'd use to type in an exponent. On any model, make sure to use the negative button, which often looks like ( - ) rather than the subtraction button for negative values. (Otherwise you might get an error message.) If the calculator reports some number E another value (also sometimes EE or with a small digit off to the far right,) that is often returning a value to you that is meant to be set in scientific notation.
