Answer 2

`x^{(7)/(3) }`

Explanation:

The given expression is

`\sqrt[3]{x^(7) }`

There's a exponent which relates fractional exponents and roots, that is

`\sqrt[n]{x^(m) } = x^{(m)/(n) }`

So, if we apply this property, the results would be

`\sqrt[3]{x^(7) }=x^{(7)/(3) }`

Therefore, the right answer is the third choice
`x^{(7)/(3) }`
