For this case we have that by definition of properties of powers, it is fulfilled:
[tex](a ^ n) ^ m = a ^ {n * m}[/tex]
So, if we have the following expression:
[tex](x^{10}) ^ {\frac {3} {5}}[/tex]
We can simplify how:
[tex]x ^ {\frac {30} {5}}\\x ^ 6[/tex]
Thus, x is raised to exponent 6.
Answer:
[tex]x ^ 6[/tex]
