Question

Fie multimile:a= 1 2 3 5,b = 0 2 4 6,si c= 1 3 6 7 8 9.calculeaza.aub,au(buc),(a\b)\c

Answer 1

Răspuns:

A U B = 0,1,2,3,4,5,6

A U(B U C) =0,1,2,3,4,5,6,7,8,9

(A-B)-C=1,2,5

Answer 2

Răspuns:

AuB={1,2,3,4,5,6}

Au(BuC) =Au{0,1,2,3,4,6,7}={1,2,3,4,5,6,7}

(A\B) \C={1,3,5}\C={5}

Sper sa fie corect :)
