Let's break this down: The sixth root of 81 = 81^(1/6) 81 is 9^2, so we have 9^(2*1/6) = 9^(1/3) or the cubed root of 9. Therefore, to get rid of the radical in the denominator, multiply by the equivalent of 1. Multiply by the cubed root of 3 divided by the cubed root of 3...

Now that I look at A, I do not see how -4 can be a root. checking 256+640+672+88*4+80 is not a root. Thatmeans neither A nor D is a root. Which means none of the answers are then right.
