Please express as a single radical?

y^1/3 x x^3/4

Would you please show me how you got the answer?

(I know the right one...but interested in seeing how the right answer is obtained)

Incidentally: Thanks to Eric S, Maine t, alwbsok and others for your efforts in answering these. You've increased my understanding.

Update:

(y^1/3) (x^3/4)

The single radical should have a square root sign.

The right answer is:

12th root, x^9y^4

but I don't know how to get there.

Incidentallly..thanks again!

    (y^1/3) (x^3/4) <== Is this what you want?

    (y^1/3) (x^3/4) = (x^9 y^4)^(1/12)

    ok u cant really do anything to this as they are different bases of x and y

    y^1/3 is the cube root of y so u can write that as little 3√ y

    x^3/4 is the 4th root of y then cubed so little 4√x^3

    =little 4√x^3*little 3√ y
