expand xy^{-4}

Solution

expand

x y^{- 4}

Solution

\frac{x}{y ^{4}}

Solution steps

x y^{- 4}

Apply exponent rule:

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

= \frac{1}{y ^{4}} x

Multiply fractions:

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

= \frac{1 \cdot x}{y ^{4}}

Multiply:

1 \cdot x = x

= \frac{x}{y ^{4}}
