6+\sqrt[3]{3x^2}=18

解答

6 + 3 3 x^{2} = 18

解答

x = 24, x = - 24

求解步骤

6 + 3 3 x^{2} = 18

将

6

到右边

3 3 x^{2} = 12

对方程式两边

3

次方:

3 x^{2} = 1728

3 x^{2} = 1728

解

3 x^{2} = 1728 : x = 24, x = - 24

x = 24, x = - 24

验证解:

x = 24

真

, x = - 24

真

解为

x = 24, x = - 24

(4 x + 4)^{\frac{1}{3}} = 2

0=sqrt(-2*20*t+144)

0 = - 2 \cdot 20 \cdot t + 144

y^{0.3}(2y+4)=8y

y^{0.3} (2 y + 4) = 8 y

sqrt((2x+3))^2+3-1=1

(2 x + 3)^{2} + 3 - 1 = 1

x^{\frac{1}{2}} = 64
