$${x}\Gamma\left({x}^{\mathrm{2}} \right)\:=\:\mathrm{5}\Gamma\left({x}\right) \\ $$$${x}^{\mathrm{2}} \Gamma\left({x}^{\mathrm{2}} \right)\:=\:\mathrm{5}{x}\Gamma\left({x}\right) \\ $$$$\Gamma\left({x}^{\mathrm{2}} +\mathrm{1}\right)\:=\:\mathrm{5}\Gamma\left({x}+\mathrm{1}\right) \\ $$$$\mathrm{no}\:\mathrm{solution}\:\mathrm{in}\:\mathbb{C} \\ $$ | ||
