9=\sqrt[3]{(8t+600)^2}

解答

9 = 3 (8 t + 600)^{2}

解答

t = - \frac{573}{8}, t = - \frac{627}{8}

+1

十进制

t = - 71.625, t = - 78.375

求解步骤

9 = 3 (8 t + 600)^{2}

对方程式两边

3

次方:

729 = 64 t^{2} + 9600 t + 360000

729 = 64 t^{2} + 9600 t + 360000

解

729 = 64 t^{2} + 9600 t + 360000 : t = - \frac{573}{8}, t = - \frac{627}{8}

t = - \frac{573}{8}, t = - \frac{627}{8}

验证解:

t = - \frac{573}{8}

真

, t = - \frac{627}{8}

真

解为

t = - \frac{573}{8}, t = - \frac{627}{8}

sqrt(5x-4)-2=sqrt(x)

5 x - 4 - 2 = x

2x^{16/5}-16x^{13/5}=0

2 x^{\frac{16}{5}} - 16 x^{\frac{13}{5}} = 0

sqrt(x)+\sqrt[3]{x}=12

x + 3 x = 12

sqrt(5-w/4)=sqrt(w+8)

5 - \frac{w}{4} = w + 8

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

x + 2 + 3 - x = 3
