x^3-x^{1/3}=0

解答

x^{3} - x^{\frac{1}{3}} = 0

解答

x = 0, x = - 1, x = 1

求解步骤

x^{3} - x^{\frac{1}{3}} = 0

去除根式

- x = - x^{9}

解

- x = - x^{9} : x = 0, x = - 1, x = 1

x = 0, x = - 1, x = 1

验证解:

x = 0

真

, x = - 1

真

, x = 1

真

解为

x = 0, x = - 1, x = 1

2=1.69sqrt(s+4.45-3.49)

2 = 1.69 s + 4.45 - 3.49

sqrt(5x-9)+13=14

5 x - 9 + 13 = 14

4(x+3)^{2/3}=36

4 (x + 3)^{\frac{2}{3}} = 36

sqrt(2x^2-5x+12)=x-4

2 x^{2} - 5 x + 12 = x - 4

x^{1/2}+x^{-1}=110

x^{\frac{1}{2}} + x^{- 1} = 110
