Staff Review
In this video, you will learn how to evaluate expressions of logarithms. This is very similar to the previous video, but now you will obtain actual numerical values for the expressions. Several rules and properties of logarithms come in handy in these problems, and some tricks are necessary to use the information given to simplify. In some of these problems, there are multiple ways to arrive at the same answer.
