I have removed all annotations from my videos that were used to correct errors (YouTube is
getting rid of Annotattions) Any errors in the videos have been corrected in the NOTES.

X^2=16 is not an exponential equation. In an Exponential Equation the variable is at the exponent.
In part I of this series, I give you a number of examples of exponential equations that can be solved
without using logarithms. For example 2^X=16.
In this second part, I explain how to solve exponential equations like 2^X=3 that need logarithms.
