Question

a.Demonstrati ca M41 intersectat M159 intersectat N* =taiat nu multimea vida b.Demonstrati ca M33 intersectat M111 intersectat N* =taiat nu multimea vida

Answer 1

a) [41, 159] = 6519
$M_{41}\cap M_{159}=M_{6519}$
$M_{6519}\cap\mathbb{N}\neq\oslash$

b) [33, 111] = 1221
$M_{33}\cap M{111}=M_{1221}$
$M_{1221}\cap\mathbb{N}\neq\oslash$
