2.5E-16=(x^2)/(0.76)

解

2.5 E - 16 = \frac{x ^{2}}{0.76}

x = \frac{19}{1.0 E 17}, x = - \frac{19}{1.0 E 17}

十進法表記

x = 1.3784 E - 8, x = - 1.3784 E - 8

解答ステップ

2.5 E - 16 = \frac{x ^{2}}{0.76}

辺を交換する

\frac{x ^{2}}{0.76} = 2.5 E - 16

以下で両辺を乗じる:

0.76

x^{2} = 1.9 E - 16

x^{2} = f (a)

の場合, 解は

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

x = 1.9 E - 16, x = - 1.9 E - 16

1.9 E - 16 = \frac{19}{1.0 E 17}

- 1.9 E - 16 = - \frac{19}{1.0 E 17}

x = \frac{19}{1.0 E 17}, x = - \frac{19}{1.0 E 17}
