-49/16+15/2 =d^2

解

- \frac{49}{16} + \frac{15}{2} = d^{2}

d = \frac{71}{4}, d = - \frac{71}{4}

十進法表記

d = 2.10653 \dots, d = - 2.10653 \dots

解答ステップ

- \frac{49}{16} + \frac{15}{2} = d^{2}

辺を交換する

d^{2} = - \frac{49}{16} + \frac{15}{2}

簡素化

- \frac{49}{16} + \frac{15}{2} : \frac{71}{16}

x^{2} = f (a)

の場合, 解は

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

d = \frac{71}{16}, d = - \frac{71}{16}

\frac{71}{16} = \frac{71}{4}

- \frac{71}{16} = - \frac{71}{4}

d = \frac{71}{4}, d = - \frac{71}{4}
