Answer:
Choice A. √x
Step-by-step explanation:
In exponents,
![\\ \tt \: {a}^{ \frac{1}{b} } = \sqrt[b]{a}](https://tex.z-dn.net/?f=%20%20%5C%5C%20%20%5Ctt%20%5C%3A%20%20%7Ba%7D%5E%7B%20%5Cfrac%7B1%7D%7Bb%7D%20%7D%20%20%3D%20%20%5Csqrt%5Bb%5D%7Ba%7D%20)
Hence,
![\\ \tt \: {x}^{ \frac{1}{2} } = \sqrt[2]{x} \: \: \: or \: \: \: \sqrt{x}](https://tex.z-dn.net/?f=%20%5C%5C%20%20%5Ctt%20%5C%3A%20%20%20%7Bx%7D%5E%7B%20%5Cfrac%7B1%7D%7B2%7D%20%7D%20%20%3D%20%20%5Csqrt%5B2%5D%7Bx%7D%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20or%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5Csqrt%7Bx%7D%20)
