h^3=0.027

解答

h^{3} = 0.027

解答

h = \frac{3}{10}, h = - \frac{3}{20} + \frac{3 3}{20} i, h = - \frac{3}{20} - \frac{3 3}{20} i

求解步骤

h^{3} = 0.027

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}

h = 3 0.027, h = 3 0.027 \frac{- 1 + 3 i}{2}, h = 3 0.027 \frac{- 1 - 3 i}{2}

3 0.027 = \frac{3}{10}

化简

3 0.027 \frac{- 1 + 3 i}{2} : - \frac{3}{20} + \frac{3 3}{20} i

化简

3 0.027 \frac{- 1 - 3 i}{2} : - \frac{3}{20} - \frac{3 3}{20} i

h = \frac{3}{10}, h = - \frac{3}{20} + \frac{3 3}{20} i, h = - \frac{3}{20} - \frac{3 3}{20} i
