For this case we must find an expression equivalent to:

\frac {\sqrt [7] {x ^ 2}} {\sqrt [5] {y ^ 3}}

By definition of properties of powers and roots we have:

\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}

So, rewriting the expression we have:

\frac {x ^ {\frac {2} {7}}} {y ^ {\frac {3} {5}}} =

By definition of power properties we have:

a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}

So:

x ^ {\frac {2} {7}} * y ^ {- \frac {3} {5}}
