$x^{- 3} y^{4} - x^{2} y^{- 4}$

Step 1

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

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

Step 2

Combine $\frac{1}{x^{3}}$ and $y^{4}$ .

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

Step 3

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

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

Step 4

Combine $\frac{1}{y^{4}}$ and $x^{2}$ .

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