Question

A = {x apartineN*|x < 16}
B = {x apartine N*| x^3 < 64} Calculează:
A ᑎ B =
A ᑌ B =
A\B =
B\ Α =​

Answer 1

A={1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}

B={1, 2, 3}

A ᑎ B={1, 2, 3}- intersectia multimilor

A ᑌ B={1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}- reuniunea multimilor

A\B={4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}- diferenta multimilor

B\A=Ø- multimea vida, nu are niciun element
