$\frac{3^{2} x^{- 3} y^{- 4}}{2^{- 1} x^{- 4} y^{- 5}}$

Step 1

Move $x^{- 4}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$\frac{3^{2} x^{- 3} y^{- 4} x^{4}}{2^{- 1} y^{- 5}}$

Step 2

Move $y^{- 5}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$\frac{3^{2} x^{- 3} y^{- 4} x^{4} y^{5}}{2^{- 1}}$

Step 3

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

$3^{2} x^{- 3} y^{- 4} x^{4} y^{5} \cdot 2$

Step 4

Multiply $x^{- 3}$ by $x^{4}$ by adding the exponents.
