Showing how to find the inverse of an exponential to find the log, y = 2^x

The video tutorial explains the concept of inverse functions, focusing on how to find the inverse of exponential equations using logarithms. It begins by discussing the confusion around inverses and the use of roots as inverse operations. The tutorial then introduces logarithms as a way to express inverses, specifically for equations like y = 2^x. The instructor emphasizes understanding the relationship between exponential functions and their inverses, using logarithms to solve for variables. The video concludes with a summary of how logarithms represent the inverse of exponential equations.
