Understanding Coefficients and Exponents

This video tutorial covers the rules for converting negative exponents to positive ones. It explains the concepts of base and coefficient, and how they interact with exponents. The tutorial provides examples of flipping fractions to their reciprocals to change the sign of exponents. It emphasizes the importance of understanding these rules for simplifying expressions and prepares students for applying these rules in future lessons.
