Description
This video looks at Index Laws 1 and 2. I take time to show not only what the laws are, but how they are created. I think it's really important to ensure that you understand what you are doing! There are lots of worked examples which show you how to use Laws 1 and 2. Using a mix of humour and explanation I hope to ensure that the Mathematics taught in this topic is entertaining and helpful for all levels of students.
