simplify (-2x)^{-1}

Solution

simplify

(- 2 x)^{- 1}

Solution

- \frac{1}{2 x}

Solution steps

(- 2 x)^{- 1}

Apply exponent rule:

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

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

= \frac{1}{- 2 x}

Apply the fraction rule:

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

= - \frac{1}{2 x}

Popular Examples

5 x^{2} + 5 x - 3 = 2 x^{2}

factor ((1/4 x^2+ax+(2a-8)-8))/(2(x+2))factor

\frac{( \frac{1}{4} x ^{2} + a x + ( 2 a - 8 ) - 8 )}{2 ( x + 2 )}

- x^{2} - x + 2 = 0

simplify 16.5*1/10 simplify

16.5 \cdot \frac{1}{10}

8x<24\lor x-4>1

8 x < 24 or x - 4 > 1
