Question

Cine ma poate ajuta ?

Answer 1

$\frac{ \sqrt{3}- \sqrt{2} }{ \sqrt{2} - \sqrt{3} }= \frac{ (\sqrt{3}- \sqrt{2})( \sqrt{2}+ \sqrt{3}) }{ (\sqrt{2}- \sqrt{3})( \sqrt{2}+ \sqrt{3}) } = \frac{3-2}{2-3}=-1$
$\frac{ \sqrt{3}- \sqrt{2} }{ \sqrt{2}- \sqrt{3} }= \frac{-( \sqrt{2}- \sqrt{3}) }{ \sqrt{2}- \sqrt{3} } =-1$
