Answer

$7\sqrt 7+7\sqrt 5$

Work Step by Step

Multiply the numerator and the denominator by the conjugate of the denominator to rationalize the denominator. Then divide to simplify completely. $\frac{14}{\sqrt 7-\sqrt 5}$ $\frac{14}{\sqrt 7-\sqrt 5}*\frac{\sqrt 7+\sqrt 5}{\sqrt 7+\sqrt 5}$ $\frac{14\sqrt 7+14\sqrt 5}{2}$ $7\sqrt 7+7\sqrt 5$
