    Re: Dividing Radicals #2

    Remember that

    \sqrt[n]{\frac{a}{b}}=\frac{\sqrt[n]{a}}{\sqrt[n]{b}}

    With that in mind you can express

    \sqrt{\frac{5}{12}} as \frac{\sqrt{5}}{\sqrt{12}} 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.

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