Question

Va rog urgent dau coroana ​

Answer 1

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!
