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

解答

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}

十进制

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

求解步骤

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

化简

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

对于

x^{2} = f (a)

解为

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}

s im pl i f y - 3 - (- 1)

f a c t or x^{2} + 4 x y - 117 y^{2}

s im pl i f y \frac{5 π}{12} + \frac{π}{12}

x^{2} - 6 = 3

130000 = (400 - x)^{2}
