Lesson Summary:
In this lesson on logarithms, we learn about the power property of logs and how to use it to simplify expressions. The power property of logs states that the log of a base b of a to the n is equal to n times the log of a base b. By using this property, we can rewrite expressions and solve problems involving logarithms more easily. The lesson provides examples and practice problems to help solidify the concept.
