Description
This video looks at the final two Index laws; namely, Index Law 4 and 5. These look at extending the laws we have previously discovered. Using Rule 3, we can adapt it to help us use index laws with Fractions! I know .. who likes fractions, right? But I show how to make it easy with lots of worked examples and explanations which just make sense!
