Question

1) são dados os conjuntos:
A = {x e N / x é ímpar},
B = {x e Z / -3 < x < 4},
C = {x e Z / x < 6}.

a) (A∩B) U (B∩C) =
b) (A∩C) U B =

PFVR ME AJUDEM É PRA HOJEEEE!!!!

Answer 1

A={x ∈ N | x é ímpar}

B = {x ∈ Z | -3 ≤x<4} ={-3,-2,1,0,1,2,3}

C = {x ∈ Z | < 6}

a)  (A∩B)U(B∩C) = {1,2,3} U {-3,-2,-1,0,1,2,3}

= {-3,-2,-1,0,1,2,3}

b) (A∩C) U B =

{ 1,2,3,4,5} U {-3,-2,1,0,1,2,3}

={-3,-2,1,0,1,2,3,4,5}
