\[\textbf{а)}\ 5\sqrt{2} + 3\sqrt{5}\ и\ 3\sqrt{7} + \sqrt{45}\]

\[\sqrt{50} + 3\sqrt{5}\ и\ \sqrt{63} + 3\sqrt{5}\]

\[\sqrt{50} > \sqrt{63}\]

\[5\sqrt{2} + 3\sqrt{5} < 3\sqrt{7} + \sqrt{45}.\]

\[\textbf{б)}\ 6\sqrt{2} - 2\sqrt{7}\ и\ 4\sqrt{3} - \sqrt{28}\]

\[\sqrt{72} - 2\sqrt{7}\ и\ \sqrt{48} - 2\sqrt{7}\]

\[\sqrt{72} > \sqrt{48}\]

\[6\sqrt{2} - 2\sqrt{7} > 4\sqrt{3} - \sqrt{28}.\]

\[\textbf{в)}\ 5\sqrt{3} + 3\sqrt{5}\ \ и\ \sqrt{75} + 7\sqrt{2}\ \]

\[5\sqrt{3} + \sqrt{45}\ и\ 5\sqrt{3} + \sqrt{98}\]

\[\sqrt{45} < \sqrt{98}\]

\[5\sqrt{3} + 3\sqrt{5} < \sqrt{75} + 7\sqrt{2}.\]

\[\textbf{г)}\ \sqrt{112} - 2\sqrt{5}\ и\ 4\sqrt{7} - \sqrt{23}\ \]

\[4\sqrt{7} - \sqrt{20}\ и\ 4\sqrt{7} - \sqrt{23}\]

\[\sqrt{20} < \sqrt{23}\]

\[\sqrt{112} - 2\sqrt{5} > 4\sqrt{7} - \sqrt{23}.\]
