Answer: Choice ARaising something to the 1/4th power is the same as applying the 4th root to that expression. Raising an expression to the 1/n power is the same as applying the nth root.
Rule:
![x^(1/n) = \sqrt[n]{x}](https://img.qammunity.org/2019/formulas/mathematics/middle-school/kldp0qtfvk4858e13z6j3zt6oys9b3sf2t.png)
(if the text is too small it basically says x to the (1/n) = square root with a small 'n' all over x)
