Introduction
The index laws
Exponential functions and logarithms
Year 11
Have you wondered why numbers float? What is an exponent any way? Why is an exponent also called an Index? What's all this powers stuff? Well, this video is here to demystify the mysterious worlds of index laws and exponents. OK. I call them floaty numbers as they are numbers what float! Every one else calls them indices. You say potato and I say ... well ... potato to be honest. In this video I take a look at how to multiply terms with indices, divide terms with indices, explain that the zero index is and why it is always one. I look at the product rule and the quotient rule all within about 15 minutes. If you want to know everything there is to know about powers/indices/indexs'/floaty numbers ... then watch the video!
