78.2^2+41.3^2=c^2

解

78. 2^{2} + 41. 3^{2} = c^{2}

c = \frac{782093}{10}, c = - \frac{782093}{10}

十進法表記

c = 88.43602 \dots, c = - 88.43602 \dots

解答ステップ

78. 2^{2} + 41. 3^{2} = c^{2}

辺を交換する

c^{2} = 78. 2^{2} + 41. 3^{2}

簡素化

78. 2^{2} + 41. 3^{2} : 7820.93

x^{2} = f (a)

の場合, 解は

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

c = 7820.93, c = - 7820.93

7820.93 = \frac{782093}{10}

- 7820.93 = - \frac{782093}{10}

c = \frac{782093}{10}, c = - \frac{782093}{10}
