Question

simplify the expression.

Answer 1

\[\frac{ 7 }{\sqrt{11} -\sqrt{7}}\]

Answer 2

\[\large \frac{ 7 }{\sqrt{11} -\sqrt{7}}\]


\[\large \frac{ 7(\sqrt{11}+\sqrt{7}) }{(\sqrt{11} -\sqrt{7})(\sqrt{11}+\sqrt{7})}\]


\[\large \frac{ 7\sqrt{11}+7\sqrt{7} }{(\sqrt{11})^2 -(\sqrt{7})^2}\]


\[\large \frac{ 7\sqrt{11}+7\sqrt{7} }{11-7}\]


\[\large \frac{ 7\sqrt{11}+7\sqrt{7} }{4}\]
