Which expression is equivalent to

For this case we must indicate an expression equivalent to:
[tex]x ^ {- \frac {5} {3}}[/tex]
By definition of power properties we have to:
[tex]a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}[/tex]
Then, we can rewrite the expression as:
[tex]\frac {1} {x ^ {\frac {5} {3}}}[/tex]
We also have that by definition of properties of powers it is fulfilled that:
[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]
Then, the expression is like:
[tex]\frac {1} {\sqrt [3] {x ^ 5}}[/tex]
