Which expression is equivalent to `\left(x^{\frac{3}{7}}\right)^{2}`
Answer choices: x^{\frac{5}{7}}, x^{\frac{6}{14}}, x^{\frac{6}{7}}, x^{\frac{7}{17}}, x^{\frac{6}{14}}
The expression `\left(x^{\frac{3}{7}}\right)^{2}` is equivalent to `x^{\frac{3}{7} * 2} = x^{\frac{6}{7}}`.
Therefore, the correct equivalent expression is x^{\frac{6}{7}}.
Answer choice: x^{\frac{6}{7}}
