How to evaluate using rational exponents ex 2, 8^(1/3)

The video tutorial explains how to evaluate expressions with rational exponents. It covers two methods: rewriting the expression as a radical and converting the base to an exponent. The tutorial addresses common student difficulties and provides step-by-step guidance to simplify expressions, ultimately showing that both methods lead to the same result.
