Explicație pas cu pas:
[tex]\sqrt{(\sqrt{8}-3)^{2}}+\sqrt{(5-\sqrt{18})^{2}}+\sqrt{(7-\sqrt{50})^{2}}= \sqrt{(3-\sqrt{8})^{2}}+\sqrt{(5-\sqrt{18})^{2}}+\sqrt{\sqrt{50}-7)^{2}}=|3-\sqrt{8}|+|5-\sqrt{18}|+|\sqrt{50}-7|= 3-\sqrt{8}+5-\sqrt{18}+\sqrt{50}-7= 3-\sqrt{4*2}+5-\sqrt{9*2}+\sqrt{25*2}-7=3-2\sqrt{2}+5-3\sqrt{2}+5\sqrt{2} -7=1- 5\sqrt{2} +5\sqrt{2} =1[/tex]
