Follow the rules of PEMDAS to simplify an expression with multiple rules of exponents

The video tutorial guides students through simplifying mathematical expressions using the order of operations, focusing on simplifying within parentheses, applying the quotient rule, and handling negative exponents. The instructor demonstrates each step, emphasizing the importance of converting negative exponents to positive and distributing powers across quotients and products. The final expression is simplified to a positive exponent form.

Explain how to rewrite an expression with negative exponents to make them positive.
