Properties of Logs

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.

In this video I go over the properties of logs which will be very useful in the next videos to come, to solve exponential equations. To solve exponential equations like 2^x=16 we don't need logs but, to solve exponential equations like 2^x=3 we do need logs. I include the change of base formula which will allow you to use your calculator to do things like calculating the log of 8 on base 2. Finally, I give you a number of exercises using the properties of logs.
