    Even though the introduction says that this is part 11, this is actually part 16 of logarithms. Several example problems are shown and solved. The problems in this video are logarithmic equations in which you need to find the value of x, which is inside of a logarithm. The properties of logarithms are used to help solve these problems. All work is shown and explained in this lesson.
