About Course

INDICES AND ROOTS SERIES

Welcome to the SumNation series on Indices and Roots, where multiplication and division go into overdrive.

We’ll start off nice n’ easy by understanding what indices are, the glorious forms they come in and the operations that can be performed on them (not surgery, I mean times and divide)

We’ll then power on into the world of roots, find out what they are and understand the relationship with powers, addressing a very specific and irrational species of roots called surds.

What Will You Learn?

  • You'll know what indices are and how to manipulate them (good manipulation)
  • You'll understand the importance of standard form (Indices celebrity basically)
  • You'll understand the relationship between indices, roots and surds
  • You'll know how to work with surds
  • You'll know why and how we rationalise fractions with surds (You're rational right..?)
