Simplify (2x^-3y^-2)/(z^4)

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

Move $x^{- 3}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

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

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

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