-1/(x^2)=x^2

Lösung

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

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

- 1 = x^{4} : x = \frac{1}{2} + \frac{1}{2} i, x = - \frac{1}{2} - \frac{1}{2} i, x = \frac{1}{2} - \frac{1}{2} i, x = - \frac{1}{2} + \frac{1}{2} i

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

3 + \frac{10}{z} = \frac{1}{2}

\frac{x}{12} = \frac{3}{x}

0 = \frac{- 0.75 s + 2.5}{( s - 3 ) - 1}

1000 = \frac{1200}{( 1 + r ) ^{5}}

\frac{20}{x + 7} = \frac{4}{5}
