簡約 2(-3)+3/((-2))+(-(2))/((-sqrt(16)))

解

簡約

2 (- 3) + \frac{3}{( - 2 )} + \frac{- ( 2 )}{( - 16 )}

- 7

解答ステップ

2 (- 3) + \frac{3}{- 2} + \frac{- ( 2 )}{- 16}

規則を適用する:

- (a) = - a

- (2) = - 2

= 2 (- 3) + \frac{3}{- 2} + \frac{- 2}{- 16}

2 (- 3) = - 6

\frac{3}{- 2} = - \frac{3}{2}

\frac{- 2}{- 16} = \frac{2}{4}

= - 6 - \frac{3}{2} + \frac{2}{4}

- 6 - \frac{3}{2} + \frac{2}{4} = - 7

= - 7
