Understanding Rational Exponents and Powers

This video tutorial reviews rational exponents, focusing on their properties and how to manipulate and simplify expressions using them. It begins with a review of basic exponent rules, including multiplication, division, power of a power, and negative exponents. The tutorial then explains rational exponents, how to convert them to radical form, and provides examples to illustrate these concepts. The video concludes with verification of examples and a summary of the key points discussed.
