How to evaluate a number to a negative rational power

The video tutorial explains how to evaluate expressions using rational exponents. It begins by addressing negative exponents and how to rewrite them as positive exponents. The tutorial then focuses on evaluating 64 to the 2/3 power, discussing the use of roots and powers. It emphasizes simplifying expressions by rewriting 64 as a power of 4, using exponent rules to make calculations easier. The tutorial concludes with the final calculation, demonstrating the process of evaluating the expression to arrive at the result of 1/16.
