0.548983=[1-((1-c)/(0.2))^2]

解

0.548983 = [1 - (\frac{1 - c}{0.2})^{2}]

解

c = 1 - 0.2 0.451017, c = 1 + 0.2 0.451017

+1

十進法表記

c = 0.86568 \dots, c = 1.13431 \dots

解答ステップ

0.548983 = [1 - (\frac{1 - c}{0.2})^{2}]

辺を交換する

[1 - (\frac{1 - c}{0.2})^{2}] = 0.548983

1 - (\frac{1 - c}{0.2})^{2} = 0.548983

1

を右側に移動します

- (\frac{1 - c}{0.2})^{2} = - 0.451017

以下で両辺を割る

- 1

(\frac{1 - c}{0.2})^{2} = 0.451017

(g (x))^{2} = f (a)

の場合, 解は

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

解く

\frac{1 - c}{0.2} = 0.451017 : c = 1 - 0.2 0.451017

解く

\frac{1 - c}{0.2} = - 0.451017 : c = 1 + 0.2 0.451017

二次equationの解:

c = 1 - 0.2 0.451017, c = 1 + 0.2 0.451017
