x^2=-196

解答

x^{2} = - 196

x = 14 i, x = - 14 i

求解步骤

x^{2} = - 196

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

x = - 196, x = - - 196

- 196 = 14 i

- - 196 = - 14 i

x = 14 i, x = - 14 i

e^{x^{2}} \cdot e^{- x^{2}}

6 b^{2} + 4 b = 130

20 k^{2} + 110 k + 120

\frac{3}{2} + \frac{2}{5} - \frac{7}{4}

3105 = 27 (p + 30)
