Applying the quotient rule to simplify a rational expression

The video tutorial explains how to apply the rules of exponents to simplify expressions. It covers the basic rules: adding powers when multiplying, subtracting powers when dividing, and using reciprocals for negative exponents. The tutorial demonstrates these rules by simplifying expressions with the same base and reducing fractions, leading to a final simplified answer.
