Hello there !

$\frac{4 \sqrt{3} +5\sqrt{2}}{ \sqrt{48} + \sqrt{18} }$

Rationalising the denominator 

$\frac{ 4\sqrt{3} +5\sqrt{2} }{ \sqrt{48}+ \sqrt{18} } X\frac{ \sqrt{48}- \sqrt{48} }{ \sqrt{18} - \sqrt{18} }$

$\frac{48 - 4 \sqrt{3}( 3\sqrt{2})+ 5 \sqrt{2} ( 4\sqrt{3} )-30 }{30}$

$\frac{48 - 12 \sqrt{6} +20 \sqrt{6}-30 }{30}$

$\frac{48-30+8 \sqrt{6} }{30}$

$\frac{18+8 \sqrt{6} }{30}$
