Lesson Summary:
In this lesson on logarithms, the instructor covers three basic properties of logarithms, including the log of 1 base, the log of B to the x base B, and B log base B of x. By using these properties, the instructor simplifies several logarithmic equations and provides examples for the viewer to try on their own. The lesson concludes with a summary of the basic properties of logarithms and a teaser for the next lesson to come.
Lesson Description:

Staff Review
This lesson explains the basic properties of logarithms and shows you the formulas for the rules. It also shows why these properties exist and where they come from. These rules / properties are then used to simplify 9 logarithmic expressions. Make sure to watch the other videos in this series if you do not understand anything in this lesson. The properties make the problems in this lesson relatively simple.
