Warm Up
Using the sheet you were given on the way in,
see if you can come up with the properties of
exponents with your group.
Today’s Objectives
• Students will review properties of exponents
and use them to rewrite exponential
expressions.
Properties of Exponents
• In CCM1, you learned about the properties of
exponents. In your groups, complete the Equivalent
Forms of Exponential Expressions handout and
summarize each property.

Solving Exponential Equations
We’ve learned how to simplify exponential expressions
in the past and reviewed those just now. Now we
need to use those properties to find some missing
values.
