$\frac{x^{5} y^{2} z^{8}}{{(x y)}^{- 3}}$

Step 1

Move ${(x y)}^{- 3}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$x^{5} y^{2} z^{8} {(x y)}^{3}$

Step 2

Apply the product rule to $x y$ .

$x^{5} y^{2} z^{8} (x^{3} y^{3})$

Step 3

Multiply $x^{5}$ by $x^{3}$ by adding the exponents.
