0.0000013=(x^2)/(0.1)

解

0.0000013 = \frac{x ^{2}}{0.1}

x = \frac{13}{10000}, x = - \frac{13}{10000}

十進法表記

x = 0.00036 \dots, x = - 0.00036 \dots

解答ステップ

0.0000013 = \frac{x ^{2}}{0.1}

辺を交換する

\frac{x ^{2}}{0.1} = 0.0000013

以下で両辺を乗じる:

0.1

x^{2} = 0.00000013

x^{2} = f (a)

の場合, 解は

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

x = 0.00000013, x = - 0.00000013

0.00000013 = \frac{13}{10000}

- 0.00000013 = - \frac{13}{10000}

x = \frac{13}{10000}, x = - \frac{13}{10000}
