$$\sqrt{\sqrt{{x}}\:^{\mathrm{log}\:{x}} }=\:{x} \\ $$$${x}^{\frac{\mathrm{1}}{\mathrm{2}}×\frac{\mathrm{1}}{\mathrm{2}}×\mathrm{log}{x}} =\:{x} \\ $$$${x}^{\frac{\mathrm{1}}{\mathrm{2}}×\frac{\mathrm{1}}{\mathrm{2}}×\mathrm{log}{x}} =\:{x} \\ $$$${x}\:=\:\mathrm{1}\:\mathrm{or}\:\frac{\mathrm{1}}{\mathrm{4}}\mathrm{log}{x}\:=\:\mathrm{1} \\ $$$${x}\:=\:\mathrm{1}\:\mathrm{or}\:{x}\:=\:\mathrm{10}^{\mathrm{4}} \\ $$

$$\mathrm{10}^{\mathrm{4}} =\mathrm{x} \\ $$
