$\frac{p^{3} q^{\frac{5}{2}}}{q^{2} r^{- 6}}$

Step 1

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

$\frac{p^{3} q^{\frac{5}{2}} q^{- 2}}{r^{- 6}}$

Step 2

Move $r^{- 6}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$p^{3} q^{\frac{5}{2}} q^{- 2} r^{6}$

Step 3

Multiply $q^{\frac{5}{2}}$ by $q^{- 2}$ by adding the exponents.
