Solving an exponential equation by taking the log of both sides

The video tutorial explains how to solve exponential equations using different methods, including the one-to-one property and logarithms. It starts with basic exponent concepts and progresses to solving equations with non-integer solutions. The tutorial emphasizes the use of logarithms, particularly the change of base formula, to find solutions. Multiple methods are discussed, allowing learners to choose the approach that suits them best.

Describe the process of using the change of base formula for logarithms as mentioned in the text.
