1530= 1/20.55(58.37496^2+x^2)

解答

1530 = \frac{1}{2} \cdot 0.55 \cdot (58.3749 6^{2} + x^{2})

解答

x = \frac{2.156 E 15}{1000000000000}, x = - \frac{2.156 E 15}{1000000000000}

+1

十进制

x = 46.43275 \dots, x = - 46.43275 \dots

求解步骤

1530 = \frac{1}{2} \cdot 0.55 (58.3749 6^{2} + x^{2})

交换两边

\frac{1}{2} \cdot 0.55 (58.3749 6^{2} + x^{2}) = 1530

化简

\frac{1}{2} \cdot 0.55 : \frac{0.55}{2}

\frac{0.55}{2} (58.3749 6^{2} + x^{2}) = 1530

在两边乘以

2

0.55 (3407.63595 \dots + x^{2}) = 3060

两边除以

0.55

3407.63595 \dots + x^{2} = \frac{3060}{0.55}

将

3407.63595 \dots

到右边

x^{2} = \frac{3060}{0.55} - 3407.63595 \dots

化简

x^{2} = 2156.00040 \dots

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

x = 2156.00040 \dots, x = - 2156.00040 \dots

2156.00040 \dots = \frac{2.156 E 15}{1000000000000}

- 2156.00040 \dots = - \frac{2.156 E 15}{1000000000000}

x = \frac{2.156 E 15}{1000000000000}, x = - \frac{2.156 E 15}{1000000000000}
