The answer is choice A and here's why
The 2/5 outer most exponent means that we can break it down into 2*(1/5). The 2 is going to apply as an exponent for the whole parenthesis group. The 1/5 indicates we have a 5th root (similar to a square root or cube root,but instead of 2 or 3, it's 5)
In essence, I'm saying that![\LARGE x^{m/n} = \sqrt[n]{x^m}](https://tex.z-dn.net/?f=%5CLARGE%20x%5E%7Bm%2Fn%7D%20%3D%20%5Csqrt%5Bn%5D%7Bx%5Em%7D)
