sqrt(64-x^2)+sqrt(36-x^2)=10

解答

64 - x^{2} + 36 - x^{2} = 10

解答

x = \frac{24}{5}, x = - \frac{24}{5}

+1

十进制

x = 4.8, x = - 4.8

求解步骤

64 - x^{2} + 36 - x^{2} = 10

去除平方根

5184 = 14400 - 400 x^{2}

解

5184 = 14400 - 400 x^{2} : x = \frac{24}{5}, x = - \frac{24}{5}

x = \frac{24}{5}, x = - \frac{24}{5}

验证解:

x = \frac{24}{5}

真

, x = - \frac{24}{5}

真

解为

x = \frac{24}{5}, x = - \frac{24}{5}

x^{\frac{1}{3}} = 7

sqrt(x-33)=3-sqrt(x)

x - 33 = 3 - x

sqrt(3-3x)-sqrt(3x+2)=3

3 - 3 x - 3 x + 2 = 3

sqrt(s^2-1)=sqrt(5s-5)

s^{2} - 1 = 5 s - 5

sqrt(2m+1)=1+sqrt(m)

2 m + 1 = 1 + m
