Solving an exponential equation

The video tutorial explains how to solve an exponential equation, E to the X - 9 = 20, by first adding 9 to both sides to get E to the X = 29. It then explores two methods: using one-to-one properties by taking the natural logarithm (Ln) of both sides, and rewriting the equation into exponential form. The tutorial emphasizes that the choice of method depends on personal preference. Finally, it calculates the natural logarithm of 29 to find that X is approximately 3.37, concluding with a summary of the process.
