This video tutorial covers rational exponents and radical functions, reviewing properties of exponents, including zero and negative exponents. It explains the product and quotient of powers, properties of radicals, and techniques for simplifying radical expressions. The tutorial also discusses using conjugates to rationalize denominators and handling variable expressions with absolute values. The session concludes with final examples and a summary of key points.
