$p (q^{- 2}) (r^{- 3})$

Step 1

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

$p \frac{1}{q^{2}} r^{- 3}$

Step 2

Combine $p$ and $\frac{1}{q^{2}}$ .

$\frac{p}{q^{2}} r^{- 3}$

Step 3

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

$\frac{p}{q^{2}} \cdot \frac{1}{r^{3}}$

Step 4

Combine.

$\frac{p \cdot 1}{q^{2} r^{3}}$

Step 5

Multiply $p$ by $1$ .

$\frac{p}{q^{2} r^{3}}$
