(63*4)/(8+4.5)=(x)^2

解

\frac{63 \cdot 4}{8 + 4.5} = (x)^{2}

x = \frac{6 14}{5}, x = - \frac{6 14}{5}

十進法表記

x = 4.48998 \dots, x = - 4.48998 \dots

解答ステップ

\frac{63 \cdot 4}{8 + 4.5} = x^{2}

辺を交換する

x^{2} = \frac{63 \cdot 4}{8 + 4.5}

簡素化

\frac{63 \cdot 4}{8 + 4.5} : \frac{252}{12.5}

x^{2} = f (a)

の場合, 解は

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

x = \frac{252}{12.5}, x = - \frac{252}{12.5}

\frac{252}{12.5} = \frac{6 14}{5}

- \frac{252}{12.5} = - \frac{6 14}{5}

x = \frac{6 14}{5}, x = - \frac{6 14}{5}
