Salut! Multimea A = Multimea B
a) A ∪ B = -4,-3,-2,-1,0,1,2,3,4 (toate elementele adunate)
b) A ∩ B = -4,-3,-2,-1,0,1,2,3,4 (toate elementele comune)
c) A - B = 0
d) B - A= 0
b) A⊂B (Adevarat)
B⊂A(Adevarat)
A⊂(A∪B) (Adevarat)
A⊂(B-A) (Fals)
Cred ca exercitiul acesta are undeva o greseala in cerinta ei, dar eu m-am conformat! :)
Multa bafta!
