Risolvi y=s^x

$$y = s ^ { x }$$

Trova s (soluzione complessa)

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

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

$$\left\{\begin{matrix}x=\frac{2\pi n_{1}i}{\ln(s)}+\log_{s}\left(y\right)\text{, }n_{1}\in \mathrm{Z}\text{, }&y\neq 0\text{ and }s\neq 1\text{ and }s\neq 0\\x\in \mathrm{C}\text{, }&\left(s=0\text{ and }y=0\right)\text{ or }\left(s=1\text{ and }y=1\right)\end{matrix}\right,$$
