$(z^(2)) / (x^(3) y^(5))$

We have: $(x^(- 3) y^(- 5)) / (z^(- 2))$

Let's express the variables as fractions:

$= ((1) / (x^(3)) cdot (1) / (y^(5))) / ((1) / (z^(2)))$

$= ((1) / (x^(3) y^(5))) / ((1) / (z^(2)))$

$= ((1) / (x^(3) y^(5))) / ((1) / (z^(2))) cdot (z^(2)) / (z^(2))$

$= ((z^(2)) / (x^(3) y^(5))) / (1)$

$= (z^(2)) / (x^(3) y^(5))$
