Simplifying Quotients with Negative Exponents

This video tutorial explains how to simplify quotients with negative exponents when the bases are not the same. It emphasizes that the quotient rule of exponents cannot be applied in such cases. Instead, the video demonstrates how to make exponents positive by moving terms across the fraction bar, changing the sign of the exponents. Several examples are provided to illustrate the process, showing step-by-step how to simplify expressions by adjusting the position of terms and evaluating the results.

Why can't the quotient rule of exponents be applied when the bases are different?

• Because the exponents are positive.

• Because the bases are positive.

• Because the bases must be the same to apply the rule.

• Because the exponents are negative.
