Riješi 2^x+x_2^xlnx=0

$$2 ^ { x } + x _ { 2 } ^ { x } \ln x = 0$$

Riješite za x_2 (complex solution)

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

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

$$x\neq 0\text{ and }x\neq 1$$

Riješite za x_2
