a^2+3.4^2=5.6^2

解

a^{2} + 3. 4^{2} = 5. 6^{2}

a = \frac{3 11}{5}, a = - \frac{3 11}{5}

十進法表記

a = 4.44971 \dots, a = - 4.44971 \dots

解答ステップ

a^{2} + 3. 4^{2} = 5. 6^{2}

3. 4^{2}

a^{2} = 19.8

x^{2} = f (a)

の場合, 解は

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

a = 19.8, a = - 19.8

19.8 = \frac{3 11}{5}

- 19.8 = - \frac{3 11}{5}

a = \frac{3 11}{5}, a = - \frac{3 11}{5}
