Rewriting Expressions with Radical and Rational Exponents

In this video tutorial, Mr. Allen explains how to work with radical forms and rational exponents, demonstrating the conversion between the two. He provides examples involving cube roots, fourth roots, and fifth roots, showing how to simplify expressions and rewrite them using rational exponents. The tutorial emphasizes the importance of understanding different forms and their benefits in mathematics.
