64b^2=9

解

64 b^{2} = 9

b = \frac{3}{8}, b = - \frac{3}{8}

十進法表記

b = 0.375, b = - 0.375

解答ステップ

64 b^{2} = 9

以下で両辺を割る

64

b^{2} = \frac{9}{64}

x^{2} = f (a)

の場合, 解は

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

b = \frac{9}{64}, b = - \frac{9}{64}

\frac{9}{64} = \frac{3}{8}

- \frac{9}{64} = - \frac{3}{8}

b = \frac{3}{8}, b = - \frac{3}{8}
