Yes, it does make sense. You are being asked to find the "cube root" of 27%2Fy%5E6
The "cube root" sign uses the same "radical" sign as the square root, but with a little 3 in the front.
You can also write the cube root as an exponent, thus:
%2827%2Fy%5E6%29%5E%281%2F3%29 You can rewrite this expression as factors.
%28%283%5E3%29%2F%28y%5E2%29%5E3%29%5E%281%2F3%29 = %28%283%5E3%29%5E%281%2F3%29%29%2F%28%28y%5E2%29%5E3%29%5E%281%2F3%29 Multiply the exponents to get: 3%2Fy%5E2
The answer is: 3%2Fy%5E2
