Simplifying Expressions and Exponents

This video tutorial covers simplifying radical expressions, focusing on rational exponents and their properties. It reviews key exponent rules, such as adding, subtracting, and multiplying exponents, and demonstrates how to simplify complex expressions using these rules. The tutorial includes examples and ends with an assignment for further practice.
