Exponential expressions are a way of representing repeated multiplication. They can be simplified by following these steps.

Step 1: Identify the base. In the previous example, it is represented as a and is written in the lower position. This is the number that will be multiplied.

Step 2: Identify the exponent. In the example, it is represented as x and is written in the higher position. This number tells you how many times the base should be multiplied.

Step 3: Set up the expression as repeated multiplication. It should show the based being multiplied as many times as the exponent indicates.

Step 4: Simplify the expression.
