$x y^{- 1} z^{- 2}$

Step 1

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$x \frac{1}{y} z^{- 2}$

Step 2

Combine $x$ and $\frac{1}{y}$ .

$\frac{x}{y} z^{- 2}$

Step 3

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{x}{y} \cdot \frac{1}{z^{2}}$

Step 4

Combine.

$\frac{x \cdot 1}{y z^{2}}$

Step 5

Multiply $x$ by $1$ .

$\frac{x}{y z^{2}}$
