Exploring Powers and Exponents in 8th Grade Math

This video tutorial by Mr. Weaver covers eighth-grade module one, lesson one on powers and exponents. It explains how to use integer exponents to represent repeated multiplication of rational numbers. The lesson includes writing products as powers, both numerically and algebraically, and emphasizes the importance of understanding negative bases and parentheses. The tutorial also covers evaluating powers using order of operations, with examples to reinforce learning.
