Evaluating a negative expression with a rational exponent ex 4, cubr root(-125)

The video tutorial explains how to evaluate expressions using rational exponents. It begins by introducing the concept of rational exponents and the importance of rewriting radicals in this form. The tutorial then demonstrates how to simplify expressions by applying the rules of exponents, specifically focusing on the example of evaluating -125 raised to the one-third power. The process involves rewriting -125 as -5 cubed and then applying the power of a power rule to simplify the expression to -5. The tutorial concludes by summarizing the steps and reinforcing the understanding of rational exponents.
