Understanding Variables and Exponents

This tutorial covers the application of exponents to variables, reviewing basic concepts of variables and how they are used in mathematical expressions. It explains how to simplify expressions involving variables and exponents, and demonstrates the multiplication of variables with exponents. The tutorial concludes with a recap of the rules for working with exponents and variables, emphasizing that the same rules apply when variables replace numerical bases.
