((43)/(42.5))n^2-n^2=3

解

(\frac{43}{42.5}) n^{2} - n^{2} = 3

n = \frac{1.99219 E 14}{781250000000}, n = - \frac{1.99219 E 14}{781250000000}

十進法表記

n = 15.96871 \dots, n = - 15.96871 \dots

解答ステップ

(\frac{43}{42.5}) n^{2} - n^{2} = 3

拡張

(\frac{43}{42.5}) n^{2} - n^{2} : 0.01176 \dots n^{2}

0.01176 \dots n^{2} = 3

以下で両辺を割る

0.01176 \dots

n^{2} = 254.99999 \dots

x^{2} = f (a)

の場合, 解は

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

n = 254.99999 \dots, n = - 254.99999 \dots

254.99999 \dots = \frac{1.99219 E 14}{781250000000}

- 254.99999 \dots = - \frac{1.99219 E 14}{781250000000}

n = \frac{1.99219 E 14}{781250000000}, n = - \frac{1.99219 E 14}{781250000000}
