Answer:
![\sqrt[n]{x^a}=x^{a/n}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5Ea%7D%3Dx%5E%7Ba%2Fn%7D)
Step-by-step explanation:
While the "law"
![\sqrt[n]{x^n}=x](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5En%7D%3Dx)
may seem more applicable, and may seem to be a special case of the law shown in the answer above, it is not true in general. For example, ...

It is D because all the numbers range from 12 to 23, with no number being extremely low or high compared this range.
You can just plug in 16 for X
F(16) when F(x)=4x-8
F(x)=4(16)-8
F(x)=64-8
F(x)=56
It is B 80. Because it is 40 x 2 = 80. Hope thishelped
