$$\sqrt{\mathrm{7}}=\sqrt{\sqrt{\mathrm{49}}}=\sqrt[{\mathrm{4}}]{\mathrm{49}}>\sqrt[{\mathrm{4}}]{\mathrm{45}} \\ $$$$\sqrt[{\mathrm{4}}]{\mathrm{45}}\overset{?} {>}\sqrt[{\mathrm{3}}]{\mathrm{11}}\Leftrightarrow\left(\sqrt[{\mathrm{4}}]{\mathrm{45}}\right)^{\mathrm{12}} =\mathrm{45}^{\mathrm{3}} >\left(\sqrt[{\mathrm{3}}]{\mathrm{11}}\right)^{\mathrm{12}} =\mathrm{11}^{\mathrm{4}} \\ $$$$\mathrm{45}^{\mathrm{3}} >\left(\mathrm{12}×\mathrm{3}\right)^{\mathrm{3}} =\mathrm{12}^{\mathrm{3}} ×\mathrm{3}^{\mathrm{3}} >\mathrm{11}×\mathrm{11}×\mathrm{11}×\mathrm{11}=\mathrm{11}^{\mathrm{4}} \\ $$$$\Leftrightarrow\sqrt[{\mathrm{4}}]{\mathrm{45}}>\sqrt[{\mathrm{3}}]{\mathrm{11}}\Rightarrow\sqrt{\mathrm{7}}>\sqrt[{\mathrm{45}}]{\mathrm{45}}>\sqrt[{\mathrm{3}}]{\mathrm{1}}\mathrm{1} \\ $$
