Question

please solve the answer​

Answer 1

Answer:

$\frac{ \sqrt{5}( \sqrt{3} - \sqrt{2} }{ (\sqrt{3} + \sqrt{2})( \sqrt{3 } - \sqrt{2)} } = \frac{ \sqrt{15} }{1} \\ = \sqrt{15 } \\ - \frac{3 \sqrt{3}( \sqrt{2} - \sqrt{5)} }{ (\sqrt{2} + \sqrt{5})( \sqrt{2} - \sqrt{5} ) } = \frac{3 \sqrt{6 } - 3 \sqrt{15} }{ - 3} \\ = - 1( \sqrt{6} - \sqrt{15} \\ = - \sqrt{6} + \sqrt{15 } \\ \\ \\ \frac{2 \sqrt{2}( \sqrt{5} - \sqrt{3} )}{ (\sqrt{5} + \sqrt{3} )( \sqrt{5} - \sqrt{3)} } \\ = 2 \sqrt{10} - 2 \sqrt{6 } \div 2 \\ = \sqrt{10} - \sqrt{6 } \\ \\ = \sqrt{15} - \sqrt{6} + \sqrt{15} + \sqrt{10} - \sqrt{6 } \\ = 2( \sqrt{15} - \sqrt{6} ) + \sqrt{10}$
