Question

daca m ati ajuta cu una dintre aceste probleme v as fi recunoscatoare

Answer 1

Cred ca e de clasa a 5-a.
37)B={2-0,4-0,6-0,8-0,4-2,6-2,8-2,,6-4,8-4, 8-6}
38) A-B={1,2,4,8}
B-A={0,3,5,9}
AΔB={0,1,2,3,4,5,8,9}
A∪B={0,1,2,3,4,5,7,8,9}
A∩B={7}
(A∪B)-(A∩B)={0,1,2,3,4,5,8,9}
deci avem egalitatea indeplinita
