6^3-x^3=0

解答

6^{3} - x^{3} = 0

解答

x = 6, x = - 3 + 33 i, x = - 3 - 33 i

求解步骤

6^{3} - x^{3} = 0

将

6^{3}

到右边

- x^{3} = - 216

两边除以

- 1

x^{3} = 216

对于

x^{3} = f (a)

解为

x = 3 f (a), 3 f (a) \frac{- 1 - 3 i}{2}, 3 f (a) \frac{- 1 + 3 i}{2}

x = 3216, x = 3216 \frac{- 1 + 3 i}{2}, x = 3216 \frac{- 1 - 3 i}{2}

3216 = 6

化简

3216 \frac{- 1 + 3 i}{2} : - 3 + 33 i

化简

3216 \frac{- 1 - 3 i}{2} : - 3 - 33 i

x = 6, x = - 3 + 33 i, x = - 3 - 33 i
