simplify 2x^{-3}

Solution

simplify

2 x^{- 3}

Solution

\frac{2}{x ^{3}}

Solution steps

2 x^{- 3}

Apply exponent rule:

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

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

= 2 \cdot \frac{1}{x ^{3}}

Apply the fraction rule:

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

= \frac{2 \cdot 1}{x ^{3}}

Multiply the numbers:

2 \cdot 1 = 2

= \frac{2}{x ^{3}}
