Videos, worksheets, games and activities to help PreCalculus students learn how to solve exponential equations with different bases.

Solving Exponential Equations with the Different Bases.

Sometimes we are given exponential equations with different bases on the terms. In order to solve these equations we must know logarithms and how to use them with exponentiation. We can access variables within an exponent in exponential equations with different bases by using logarithms and the power rule of logarithms to get rid of the base and have just the exponent.

This video explains how to solve exponential equations using logarithms. It also shows how to check your solution graphically.
