    For one of the rule, the denominator can not be radical but, how can I get rid of that?

    i can see it now, it's the ^n(radA^m) property

    in converting (2)^2/3, what is used is one of the exponential properties, am I correct?

    I got a different answer on Mathway and it is 3^3rad2/2

    you do the same process again with the cube root of 4

    Im confused with the process now. i usually multiple the denominator to the numerator but, this question is the very first that i've ever done :/

    no matter how i multiple the denominator by itself, it's still a radical :(

    you teacher wants you to get rid of the root being on the denominator. The way to cancel it is by multiplying it by itself again such as this.|dw:1442815238734:dw|

    yes, I did it that way but, the denominator came out to be ^3rad

    Well we now have the cube root of 4, we have to do the same process once again until be can simplify it off and not have a root on the denominator.

    I can see that rad8 would be 2rad2 if there isn't a 3 as the index

    Forgot to do that on the denominator otherwise you go back to the 3/(2)^(1/3)

    when you square root something, for example 4 then it is equals to 2 because 2*2 = 4 right?

    oh I see now, 2^3=8 thus, the denom is 2

    In this case is cube too meaning you need the same number 3 times and multiply it to get the answer. In this case 8 would be 2*2*2 = 8
