Simplify (x^-1y^-2)/(z^-3)

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

Step 1

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

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

Step 2

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

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

Step 3

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

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