This Instructional Activity is a part of the Lesson 6, Unit 1, Grade 8. Students extend the previous laws of exponents to include all integer exponents. Students base symbolic proofs on concrete examples to show that (𝑥𝑏)𝑎 = 𝑥𝑎𝑏 is valid for all integer exponents. The goal of this lesson is to show why the laws of exponents are correct.
