Lesson Summary:
In this lesson, we learn how to solve exponential equations by making the bases equal. The goal is to write the equation in the form where the base is the same, and then make the exponents equal in order to solve for x. We also learn how to check our answers by plugging them back into the original equation or by using a calculator to approximate the values. With practice, solving exponential equations can be fun and easy!
