simplify xy^{-3}

Solution

simplify

x y^{- 3}

Solution

\frac{x}{y ^{3}}

Solution steps

x y^{- 3}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

y^{- 3} = \frac{1}{y ^{3}}

= x \frac{1}{y ^{3}}

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{x \cdot 1}{y ^{3}}

Apply rule:

a \cdot 1 = a

x \cdot 1 = x

= \frac{x}{y ^{3}}
