We’ve started a new unit, this one on rules of exponents. Today was a review of pre-existing shortcuts, along with an introduction of some new ones.

Finally, because I want you to be able to work through this chapter without relying on the calculator, we will have a daily Powers Quiz. I will choose 10 powers from the powers reference sheet you make in today’s homework. I will ask you to evaluate them **without using the calculator** in a brief, timed quiz. We will do this **every day** through the rest of the unit, and only your **highest grade** on any one quiz will be the one used in your Unit 5 grade.
