(x^2)/(0.2)= 1/230000

解答

\frac{x ^{2}}{0.2} = \frac{1}{230000}

解答

x = \frac{2.17391 E 15}{5 1.0 E 20}, x = - \frac{2.17391 E 15}{5 1.0 E 20}

+1

十进制

x = 0.00093 \dots, x = - 0.00093 \dots

求解步骤

\frac{x ^{2}}{0.2} = \frac{1}{230000}

在两边乘以

10000

\frac{10000 x ^{2}}{0.2} = \frac{1}{23}

在两边乘以

0.2

10000 x^{2} = 0.00869 \dots

两边除以

10000

x^{2} = 8.69565 E - 7

对于

x^{2} = f (a)

解为

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

x = 8.69565 E - 7, x = - 8.69565 E - 7

8.69565 E - 7 = \frac{2.17391 E 15}{5 1.0 E 20}

- 8.69565 E - 7 = - \frac{2.17391 E 15}{5 1.0 E 20}

x = \frac{2.17391 E 15}{5 1.0 E 20}, x = - \frac{2.17391 E 15}{5 1.0 E 20}
