(0.63024)= 1/2 (10.9)(x)^2

解

(0.63024) = \frac{1}{2} (10.9) (x)^{2}

解

x = \frac{3939}{25 5 \frac{109}{10}}, x = - \frac{3939}{25 5 \frac{109}{10}}

+1

十進法表記

x = 0.34005 \dots, x = - 0.34005 \dots

解答ステップ

(0.63024) = \frac{1}{2} (10.9) x^{2}

辺を交換する

\frac{1}{2} (10.9) x^{2} = (0.63024)

\frac{1}{2} 10.9 x^{2} = 0.63024

簡素化

\frac{1}{2} (10.9) : \frac{10.9}{2}

\frac{10.9}{2} x^{2} = 0.63024

以下で両辺を乗じる:

2

10.9 x^{2} = 1.26048

以下で両辺を割る

10.9

x^{2} = \frac{1.26048}{10.9}

x^{2} = f (a)

の場合, 解は

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

x = \frac{1.26048}{10.9}, x = - \frac{1.26048}{10.9}

\frac{1.26048}{10.9} = \frac{3939}{25 5 \frac{109}{10}}

- \frac{1.26048}{10.9} = - \frac{3939}{25 5 \frac{109}{10}}

x = \frac{3939}{25 5 \frac{109}{10}}, x = - \frac{3939}{25 5 \frac{109}{10}}
