The answer is 3 seventh root of x to the fifth power.
3 x to the 5 sevenths power is [tex] 3x^{ \frac{5}{7} } [/tex]
Since [tex]x ^{ \frac{a}{b} } = \sqrt[b]{ x^{a} } [/tex], then [tex]x^{ \frac{5}{7} } = \sqrt[7]{ x^{5} } [/tex]
Therefore:
[tex]3x^{ \frac{5}{7} } =3 \sqrt[7]{ x^{5} } [/tex]
[tex]3 \sqrt[7]{ x^{5} } [/tex] is 3 seventh root of x to the fifth power.
