Answer:
First option
is the correct answer.
Step-by-step explanation:
Let us consider each part, we have number 6 inside all the roots.
First we have to find cube root of 6.
![\sqrt[3]{6} =6^\frac{1}{3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B6%7D%20%3D6%5E%5Cfrac%7B1%7D%7B3%7D)
Now we have to find square root of this value.

So, first option
is the correct answer.
Just for future reference always put ^ for exponents. The answer is y-6 though.
(y-4)(y-6) create that trinomial. You can prove that by using the FOIL algorithm
