This is a PowerPoint lesson written for my Algebra 1 classes. It was created to correspond with Section 7.3 in the Prentice Hall California Algebra 1 textbook. The lesson explains the multiplication property of exponents -- when multiplying like bases, add the exponents.
There is a video in the lesson which explains an example problem. This makes it perfect for when you have a substitute, or for home schooling, or just so you can take roll and the lesson will continue.
It addresses part of CA Standard for Alg 1 2.0:
Students understand and use such operations as taking the opposite, finding the reciprocal, taking a root and raising to a fractional power. They understand and use the rules of exponents
Common Core Standard:
Expressions and Equations 8.EE
Work with radicals and integer exponents.
A.EE.1 Know and apply the properties of integer exponents to generate equivalent numerical expressions. For example, 3^2 × 3^(–5) = 3^(–3) = 1/(3^3) = 1/27.
NOTE: Math Type 5.0 and/or Math Type 3.0 were used to create the slides.
