Here is your answer in the attachment

OR

$\frac{2}{ \sqrt{5} + \sqrt{3} } + \frac{1}{ \sqrt{3} + \sqrt{2} } - \frac{3}{ \sqrt{5} + \sqrt{2} } \\ \red{rationalising \: all \: before \: solving} \\ = \frac{2}{ \sqrt{5} + \sqrt{3} } \\ = \frac{2 \times \sqrt{5} + \sqrt{3}}{ \sqrt{5} + \sqrt{3} \times \sqrt{5} + \sqrt{3}} \\ \\ \blue{ = \sqrt{5} - \sqrt{3}} \\ \red{solving \: all \: as \: above} \\ \frac{1}{ \sqrt{3} + \sqrt{2} } \\ \blue{ = \sqrt{3} - \sqrt{2}} \\ \frac{3}{ \sqrt{5} + \sqrt{2} } \\ \blue{= \sqrt{5} - \sqrt{2}} \\ \\ now \: performing \: the \: equation \\ \\ \green{ = > \sqrt{5} - \sqrt{3} + \sqrt{3} - \sqrt{2} - \sqrt{5} - \sqrt{2} } \\ \blue{all \: will \: cancle} \\ \huge\red{so \: answer = > 0}$
