------>>>>Here is your answer<<<<--------

$➤ \frac{7}{5 \sqrt{3} - 5 \sqrt{2} }$

$➤ \frac{7}{5 \sqrt{3} - 5 \sqrt{2} } \times \frac{5 \sqrt{3} + 5 \sqrt{2} }{5 \sqrt{3} + 5 \sqrt{2} }$

$➤ \frac{7(5( \sqrt{3} + \sqrt{2} )}{( {5 \sqrt{3}) }^{2} - {(5 \sqrt{2}) }^{2} } = \frac{35( \sqrt{3} + \sqrt{2} )}{75 - 50}$

$➤ \frac{35( \sqrt{3} + \sqrt{2} )}{25} = \frac{7( \sqrt{3} + \sqrt{ 2}) }{5}$

HOPE IT HELPS YOU..
