化简-23/2 (1/(1000^2))+23/2

解答

化简

- \frac{23}{2} (\frac{1}{100 0 ^{2}}) + \frac{23}{2}

- \frac{23}{2 \cdot 100 0 ^{2}} + \frac{23}{2}

十进制

11.4999885

求解步骤

- \frac{23}{2} (\frac{1}{100 0 ^{2}}) + \frac{23}{2}

使用法则:

(a) = a

(\frac{1}{100 0 ^{2}}) = \frac{1}{100 0 ^{2}}

= - \frac{23}{2} \cdot \frac{1}{100 0 ^{2}} + \frac{23}{2}

- \frac{23}{2} \cdot \frac{1}{100 0 ^{2}} = - \frac{23}{2 \cdot 100 0 ^{2}}

= - \frac{23}{2 \cdot 100 0 ^{2}} + \frac{23}{2}

∣ x + 4 ∣ = ∣ 5 x + 2 ∣

s im pl i f y - 7112 + 7

x - \frac{2}{7} = 5

\frac{p}{2.5} - 2.8 = - 3.44

∣ 2 x - 5 ∣ \leq 13
