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.
