Answer:

Correct Answer: A

Solution:

Given, $ {{(5568\div 87)}^{\frac{1}{3}}}+{{(72\times 2)}^{\frac{1}{2}}}={{(?)}^{\frac{1}{2}}} $

$ \Rightarrow $ $ {{(64)}^{\frac{1}{3}}}+{{(144)}^{\frac{1}{2}}}={{(?)}^{\frac{1}{2}}} $
$ \Rightarrow $ $ {{(4)}^{3\times \frac{1}{3}}}+{{(12)}^{2\times \frac{1}{2}}}={{(?)}^{\frac{1}{2}}} $

$ \Rightarrow $ $ (4)+(12)={{(?)}^{\frac{1}{2}}} $
$ \Rightarrow $ $ (16)={{(?)}^{\frac{1}{2}}} $

$ \Rightarrow $ $ {{(16)}^{2}}={{(?)}^{\frac{1}{2}\times 2}}=?=256 $
