Exponents of Variables LessonThe last lesson explained how to simplify exponents of numbers by multiplying as shown below. You know that 3 squared is the same as 1 * 3 * 3. Exponents of variables work the same way  the exponent indicates how many times 1 is multiplied by the base of the exponent. Take a look at the example below. The first problem we will work on is below. It doesn't contain a variable, but it will help us to learn how to simplify a similar problem with a varable in place of the first 3. Normally, you would simplify this problem by simplifying the inside of the parentheses first: Then, simplify the exponent outside the parentheses. This method gives a correct answer, but there is an easier way.
