### Learning Outcomes

By the end of this section, you will be able to:

- Define the identity and zero properties of exponents and logarithms.
- Define the inverse property of exponents and logarithms.
- Define the one-to-one properties of exponents and logarithms.
- Define the product and quotient properties of exponents and logarithms.

This module will introduce techniques for solving exponential and logarithmic equations. In order to solve these types of equations, you’ll need to obtain the properties that allow you to rewrite logarithms, which will be defined and demonstrated in the first part of the module. It will be helpful for you to first see how the logarithmic properties compare to the familiar exponential properties, though, which is the focus of this review section.

Warm up for this module by refreshing important concepts and skills you’ll need for success. As you study these review topics, recall that you can also return to Algebra Essentials any time you need to refresh the basics.

### Recall for success

Look for red boxes like this one throughout the text. They’ll show up just in time to give helpful reminders of the math you’ll need, right where you’ll need it.
