$- 5 y^{- 2} z$

Step 1

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

$- 5 \frac{1}{y^{2}} z$

Step 2

Combine $- 5$ and $\frac{1}{y^{2}}$ .

$\frac{- 5}{y^{2}} z$

Step 3

Move the negative in front of the fraction.

$- \frac{5}{y^{2}} z$

Step 4

Combine $z$ and $\frac{5}{y^{2}}$ .

$- \frac{z \cdot 5}{y^{2}}$

Step 5

Move $5$ to the left of $z$ .

$- \frac{5 z}{y^{2}}$
