This video goes through several examples of solving Exponential equations by converting to the same base

Here is a video that goes through some examples of solving logarithmic equations

A really excellent video that goes through examples on how to solve exponential equations using logarithms.
A really excellent video that explains how to interpret worded problems and set up exponential functions to represent a situation.
This video explains how exponential functions and log functions are inverses of each other and looks at how the graphs are related.

Here is an excellent video that goes through examples on how to simplify logarithmic expressions using the Log Laws
This video clearly explains the structure of worded problems involving exponential growth

More examples of logarithmic equations. EXCELLENT PRACTICE
This video gives extra practice in going between log and exponential format.

Here are some videos from teacher in Melbourne based on Year 11 Maths Methods
