Lös y=x^z

$$y= { x }^{ z }$$

Lös ut x (complex solution)

$$x=e^{\frac{Im(z)arg(y)+iRe(z)arg(y)}{\left(Re(z)\right)^{2}+\left(Im(z)\right)^{2}}-\frac{2\pi n_{1}iRe(z)}{\left(Re(z)\right)^{2}+\left(Im(z)\right)^{2}}-\frac{2\pi n_{1}Im(z)}{\left(Re(z)\right)^{2}+\left(Im(z)\right)^{2}}}\left(|y|\right)^{\frac{Re(z)-iIm(z)}{\left(Re(z)\right)^{2}+\left(Im(z)\right)^{2}}}$$

$$n_{1}\in \mathrm{Z}$$
