Remember that

With that in mind you can express

as and solve part c) as you did in parts a) and b)

For part d) you can do something similar, but notice that here we have a cube root.

Try to solve it and let us know if you need more help. - June 15th 2013, 11:35 PMibduttRe: Dividing Radicals #2

Firstly it is 2/3 and not - 2/3 [ 1 - 1/3 = 2/3 ]
