Multiplying and Dividing Powers M8N1. Students will understand different representations of numbers including square roots, exponents, and scientific notation. Objectives: Multiply Powers. Divide Powers. Simplify variable expressions.

Multiplying Powers 22 • 22 = 22+2= 24 = 16 x9 • x = x9+1 =x10 Rule #1: When multiplying powers with the same base, ADD the exponents. 22 • 22 = 22+2= 24 = 16 x9 • x = x9+1 =x10 36 • 3-2 = 36+-2 = 34 = 81
