Lesson Summary:
In this lesson, we learn about the product, quotient, and power properties of logarithms. We practice using these properties to simplify expressions and write them as a single logarithm. The examples given range from simple to complex, allowing for a thorough understanding and application of the properties. By the end of the lesson, students should feel comfortable using these properties to solve more advanced logarithmic expressions.
Lesson Description:

Staff Review
This lesson pulls in the concepts discussed in the last two lessons (product rule and quotient rule of logarithms) together and asks you to rewrite several practice problems. All steps involved in splitting up or putting together logarithmic expressions are explained and shown in this video.
