It's choice C as the root overhead bar goes over all of (x-7) and not just the x. So you have the correct answer.
f(x) = x^4+7
y = x^4+7
x = y^4+7
y^4 = x-7
y = FourthRoot(x-7)
![y = \sqrt[4]{x-7}](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%5B4%5D%7Bx-7%7D)
f(x) = x^4+7
y = x^4+7
x = y^4+7
y^4 = x-7
y = FourthRoot(x-7)
