B={3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48}
C={2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48}
a) {3,9,
Răspuns:
A contine numereledivizibile cu 6, mai mici de 50
A={0,6,12,18.24,30,36,42,48}
B contine numerele divizibile cu 3 mai mici decat 50
{0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48}
C e formata din numerele divizibile cu 2 mai mici decat 50
C={0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48}
a. B⊂A Fals Pt ca Elementele {3,9,16,21,27,33,39,45}⊄A
b, adevarat fiinca multime A este formata numai din numere pare mai mici ca 50
c. fals pt ca elementele multimii C enumerate la pct a. nu apartin multimii
d.adevarat pt ca
{0,3,6,9,12,15,18,21,24,27,30,33,36...48}∩{0,2.4,6,8,10,12,...,48}=
{0,6,12,18,24,30,36,42,48}=A
e. adevarat pt ca BUC={0,2,3,4,6,....,48}
{2,3,6}⊂{0,2,3,4,6,...,48}
