Side note on slide 22 - The reason we rationalise the denominator. I don't think you state the point that in a practical sense it would be impossible to "divide by" an irrational number, whereas dividing an irrational number by and integer you would be able to.

Amazing resource! Thanks! Slides Page 15: 4 :: Negative and Fractional Indices Last question: If ?=1/9 ?^2, determine 3?^(?2) in the form ??^? where ?,? are constants. Should it not read ka to the n instead of kb to the n?

I am unable to go to school due to illness. Is there any way to access the teacher resources as I need to teach myself at home.

On Slide 5, question 3 the answer should be 4x(4) - 14x(3) + 6x. *(n) I meant indices.
