The concept of dividing variable expressions with the same base is explained in this lesson. The quotient rule in the law of exponents is explained with many different example problems to show how it works. Some of the examples get pretty complicated. All of these examples eventually lead to finding out what a zero exponent means. Then, many examples of simplifying variable expressions with zero exponents are explained. This video series is great to check out if you are learning how to simplify exponent expressions.
