Hey\: there!\\ \\ \\ Solution:\\ \\= \frac{1}{\sqrt{3} + \sqrt{5} + \sqrt{7}} × \frac{\sqrt{3} - \sqrt{5} - \sqrt{7}}{\sqrt{3} - \sqrt{5} - \sqrt{7}} \\ \\ Using \:Identity:\\ \\ ( a - b - c ) ( a + b + c ) = a^{2} - b^{2} - c ^{2} \\ \\ Therefore,\: We \:Get:\\ \\= \frac{\sqrt{3}- \sqrt{5} - \sqrt{7}}{(\sqrt{3})^{2} -( \sqrt{5})^{2} - (\sqrt{7})^{2}}\\ \\ = \frac{\sqrt{3} - \sqrt{5} - \sqrt{7}}{ 3 - 5 - 7}\\ \\ = \frac{\sqrt{3} - \sqrt{5} - \sqrt{7}}{ -2 - 7 }\\ \\ = \frac{\sqrt{3} - \sqrt{5} - \sqrt{7}}{-9}\\ \\ = \frac{-\sqrt{3}}{9} + \frac{\sqrt{5}}{9} + \frac{\sqrt{7}}{9}
