Lesson Summary:
In this lesson on exponential functions, the instructor focuses on solving exponential equations. It is explained that if the bases are the same, the exponents are equal, and this is the method of choice for solving. The lesson walks through multiple examples of different forms of exponential equations being solved step-by-step, including checking the answers. The importance of checking answers is also emphasized.

Staff Review
This lesson shows how to solve some very basic exponential equations. The idea that if you have an equation that looks like b^x = b^y, then x = y, and you can solve the linear equation rather easily. Not all exponential equations look like this, but the equations in this lesson all can be solved this way. All steps involved in solving are shown and explained.
