-12+3sqrt(2581)=x1.222

解答

- 12 + 32581 = x 1.222

x = \frac{1500 ( 2581 - 4 )}{611}

十进制

x = 114.90231 \dots

求解步骤

- 12 + 32581 = x \cdot 1.222

交换两边

x \cdot 1.222 = - 12 + 32581

在两边乘以

1000

1222 x = - 12000 + 30002581

两边除以

1222

x = \frac{1500 ( 2581 - 4 )}{611}

5 (2 x - 2) - 4 x = 3 (2 - x)

so l v e f or d, c = - 3 d + 58

x + (\frac{x + 5}{2}) + (\frac{x + 41}{4}) = \frac{483}{4}

so l v e f or y, \frac{( d ^{2} \cdot y )}{( d \cdot x ^{2} )} = e^{5 x}

4242 = 2200 (\frac{1 + 0.017}{12})^{12} t
