7.3^2+b^2=13^2

解

7. 3^{2} + b^{2} = 1 3^{2}

b = \frac{11571}{10}, b = - \frac{11571}{10}

十進法表記

b = 10.75685 \dots, b = - 10.75685 \dots

解答ステップ

7. 3^{2} + b^{2} = 1 3^{2}

7. 3^{2}

を右側に移動します

b^{2} = 115.71

x^{2} = f (a)

の場合, 解は

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

b = 115.71, b = - 115.71

115.71 = \frac{11571}{10}

- 115.71 = - \frac{11571}{10}

b = \frac{11571}{10}, b = - \frac{11571}{10}
