Question

Fie mulțimile : A={1,2,3,5}, B={0,2,4,6}, C={1,3,6,7,8,9}, Calculează : A reunit cu B ; B reunit cu A ; A intersectat B ; (A reunit B) intersectat C ; A reunited (B reunited C) B intersectat A ; A\B ; B\A; (A\B)\C; A\(B\C); îｍｉ ｄａțｉ ｖă ｒｏｇ ｔｅｍａ ｓａｕ ｓａｌｌ?

Answer 1

A reunit B={0,1,2,3,4,5,6}

B reunit A={0,1,2,3,4,5,6}

A intersectat B={1,2}

(A reunit B) intersectat C={0,1,2,3,4,5,6} intersectat C={1,3,6}
