Question

Wyznacz zbiory AuB,A∩B,A/B,B/A, gdy :

a) A= {0,1,2}, B= {4,5,6,7}

b)A= {1,2,3,4,5,6,7}, B={1,3,5,7,8,10}

c) A= {-4,-3,-2,-1}, B= {-1,1,-2,2,-3,3,-4,4}

Answer 1

a AUB - zbiór pusty Aróznica B =( 0,1,2,4,5,6,7) A/B=( 0 1 2) B/A=( 4 5 6 7)

b AUB = 1 3 4 7 AróżnicaB=2 4 6 8 10 A/B=3 4 B/A 5 7

c AUB= -1 -2 -3 -4 Aróżnica B= 1 2 3 4 A/B= zbiór pusty  B/A=-1 -2 -3 -4
