it takes me a long time to fully understand methods and how to solve problems and in AS maths everyone works at a super fast pace whilst im left struggling with the basics.
Can anyone recommend websites and books for edexcel??
Brilliant!! Also fractional indices... Just remember the general rules:
a^(1/2) = Square Root of a
a^(1/3) = Cubed Root of a
a^(2/3) = (Cubed Root of a)^2
So it's the denominators root of the base... Eg 1/4 means the fourth root from four... All to the power of the numerator, which would be 1..
25^(3/2) = (Root25)^3
64^(2/3) = (CubeRoot64)^2
