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...

Year 11 maths
My teacher said If x-2(square root xy)=9-4(square root 2) so since there are two square roots -2(square root xy) equals -4(square root 2) How is this possible, could the values be different and they are not equal.

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.

For a: root(-21) = root( (21)*(-1) ) = root(21) * root(-1) = root(21) * i That should get you started
