Step 1.1

Cancel the common factor.

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

Step 1.2

Rewrite the expression.

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

Step 2

Multiply $\frac{z^{2}}{y^{- 2}}$ by $1$ .

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

Step 3

Move $y^{- 2}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$z^{2} y^{2}$
