This document contains notes on laws of exponents from a math class. It discusses multiplying powers with the same base by adding the exponents, and raising a power to a power by multiplying the exponents. Students are assigned homework problems on simplifying expressions using these laws from page 207, numbers 2 through 36, and 42 through 44.
