200= 1/3x^23.142*12

解

200 = \frac{1}{3} \cdot x^{2} \cdot 3.142 \cdot 12

解

x = \frac{50 10}{1571}, x = - \frac{50 10}{1571}

+1

十進法表記

x = 3.98916 \dots, x = - 3.98916 \dots

解答ステップ

200 = \frac{1}{3} x^{2} \cdot 3.142 \cdot 12

辺を交換する

\frac{1}{3} x^{2} \cdot 3.142 \cdot 12 = 200

以下で両辺を乗じる:

1000

12568 x^{2} = 200000

以下で両辺を割る

12568

x^{2} = \frac{25000}{1571}

x^{2} = f (a)

の場合, 解は

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

x = \frac{25000}{1571}, x = - \frac{25000}{1571}

\frac{25000}{1571} = \frac{50 10}{1571}

- \frac{25000}{1571} = - \frac{50 10}{1571}

x = \frac{50 10}{1571}, x = - \frac{50 10}{1571}
