This video looks at solution of exponential equations using logarithms. It is really building on the work from previous videos of which there is a recap at the start of this video. It takes a look at how to use logs to solve exponential equations by using the law to move the index to the front of a log. A number of awesome examples are done and the use of a CAS calculator is absolutely encouraged.
There is also a discussion of how the Mathematical Methods exam might try and trick you with inequality signs.
