化简 (-(sqrt(3))/2)/(1/2)

解答

化简

\frac{- \frac{3}{2}}{\frac{1}{2}}

- 3

十进制

- 1.73205 \dots

求解步骤

\frac{- \frac{3}{2}}{\frac{1}{2}}

使用分式法则:

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

= - \frac{\frac{3}{2}}{\frac{1}{2}}

使用分式法则:

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

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

= - \frac{3 \cdot 2}{2 \cdot 1}

消掉

- \frac{3 \cdot 2}{2 \cdot 1} : - 3

= - 3

- (x - 4) \geq 4 - (5 x + 2)

6 (s^{2} 0.167 + s + 1.333) = 0
