y^2=900(13225/400-1)

解

y^{2} = 900 (\frac{13225}{400} - 1)

y = \frac{45 57}{2}, y = - \frac{45 57}{2}

十進法表記

y = 169.87127 \dots, y = - 169.87127 \dots

解答ステップ

y^{2} = 900 (\frac{13225}{400} - 1)

簡素化

900 (\frac{13225}{400} - 1) : \frac{115425}{4}

x^{2} = f (a)

の場合, 解は

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

y = \frac{115425}{4}, y = - \frac{115425}{4}

\frac{115425}{4} = \frac{45 57}{2}

- \frac{115425}{4} = - \frac{45 57}{2}

y = \frac{45 57}{2}, y = - \frac{45 57}{2}
