a^2=sqrt(30^2-0.6^2)

解

a^{2} = 3 0^{2} - 0. 6^{2}

a = \frac{4 3 ^{3} 7 4 17}{5}, a = - \frac{4 3 ^{3} 7 4 17}{5}

十進法表記

a = 5.47667 \dots, a = - 5.47667 \dots

解答ステップ

a^{2} = 3 0^{2} - 0. 6^{2}

簡素化

3 0^{2} - 0. 6^{2} : 899.64

x^{2} = f (a)

の場合, 解は

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

a = 899.64, a = - 899.64

899.64 = \frac{4 3 ^{3} 7 4 17}{5}

- 899.64 = - \frac{4 3 ^{3} 7 4 17}{5}

a = \frac{4 3 ^{3} 7 4 17}{5}, a = - \frac{4 3 ^{3} 7 4 17}{5}
