Lesson Summary:

In this lesson, we learn how to evaluate a logarithm of a fraction using properties of logarithms. By rewriting the problem as multiple logarithms using subtraction, we can solve for the answer. We also review the concept that any logarithm evaluated for 1 is always 0. Finally, we check our answer using the calculator and the laws of exponents.
