simplify x^{-3}y

Solution

simplify

x^{- 3} y

Solution

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

Solution steps

x^{- 3} y

Apply exponent rule:

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

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

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

Apply the fraction rule:

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

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

Apply rule:

1 \cdot a = a

1 \cdot y = y

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