simplify (x^{-2})/(-2)

simplify

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

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

Solution steps

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

Apply the fraction rule:

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

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

Apply exponent rule:

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

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

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

Apply the fraction rule:

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

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

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

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

(3 x + 4 y)^{2}

3 \cdot (- 4)

- 7^{3}

(2 w - 9) + (- 4 w - 5)

x - 0
