Learn How to Multiply Two Radical Expressions by Simplifying Them First

The video tutorial covers the process of factoring and simplifying expressions involving cube roots. It begins with an introduction to factoring, followed by an exploration of cube roots and how to rewrite numbers to facilitate simplification. The tutorial then demonstrates how to simplify expressions with cube roots, emphasizing the multiplication of radicands while maintaining the root. The final section focuses on the complete simplification of the expression, resulting in a concise answer. The tutorial reassures students that different approaches to simplification are acceptable.
