x^{2} = - \frac{1528.752}{0.81307831}

Für

x^{2} = f (a)

sind die Lösungen

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

x = - \frac{1528.752}{0.81307831}, x = - - \frac{1528.752}{0.81307831}

- \frac{1528.752}{0.81307831} = \frac{400 955470}{81307831} i

- - \frac{1528.752}{0.81307831} = - \frac{400 955470}{81307831} i

x = \frac{400 955470}{81307831} i, x = - \frac{400 955470}{81307831} i
