$= \frac{1+ \sqrt{3}+ \sqrt{5} }{1+ \sqrt{3}+ \sqrt{5}}+ \frac{ \sqrt{2}+ \sqrt{6} + \sqrt{10} }{1+ \sqrt{3}+ \sqrt{5} }$$(simplificam : \frac{1+ \sqrt{3}+ \sqrt{5} }{1+ \sqrt{3}+ \sqrt{5}})=>$
$=1+ \frac{ \sqrt{2}*(1+ \sqrt{3}+ \sqrt{5}) }{1+ \sqrt{3} + \sqrt{5} } (simplificam :(1+ \sqrt{3} + \sqrt{5}) cu ,1+ \sqrt{3} + \sqrt{5}=>)$
$=1+ \sqrt{2}$
