۱. $\sqrt{98} - \sqrt{50} + \sqrt{128} = 7\sqrt{2} - 5\sqrt{2} + 8\sqrt{2} = 10\sqrt{2}$

۲. $\sqrt{54} + 5\sqrt{6} = 3\sqrt{6} + 30$

۳. $\sqrt{50} - 3\sqrt{32} + 2\sqrt{18} = 5\sqrt{2} - 12\sqrt{2} + 6\sqrt{2} = 13\sqrt{2}$

۴. $2\sqrt{50} + \sqrt{32} + 3\sqrt{72} = 10\sqrt{2} + 4\sqrt{2} + 18\sqrt{2} = 32\sqrt{2}$

۵. $5\sqrt{12} - 6\sqrt{27} + 2\sqrt{48} = 10\sqrt{2} - 18 + 8\sqrt{3} = $
