Rules of Exponents and Their Applications

This video tutorial covers the rules of exponents, including multiplication, division, power, zero, negative, and fractional exponents. It explains each rule with examples and provides a detailed breakdown of why they work. The video also includes six practice SAT problems that apply these rules, offering step-by-step solutions to help students understand and solve similar problems on their own.
