expand 3/(x^{-2)}

Solution

expand

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

Solution

3 x^{2}

Solution steps

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

Apply exponent rule:

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

x^{- 2} = \frac{1}{x ^{2}}

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

Apply the fraction rule:

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

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

Apply the fraction rule:

\frac{a}{1} = a

= 3 x^{2}
