Question

dados os conjuntos
A= {0,2,4,6}
B= {1,7,5,9}
C= {1,2,5,7}
D= {1,4,6}

A) AUB =
B) BUD =
C) AUA =
D) (A∩B) UC =
E) (AUB) UC =
F) (C∩D) ∩B =

Answer 1

a) AUB={0,1,2,4,5,6,7,9} 
b) BUD={1,4,6,7,5,9}
c)  AUA= {0,2,4,6}
d) (A∩B) UC= {1,2,5,7}
e) (AUB) UC ={0,1,2,4,5,6,7,9} +{1,2,5,7}={0,1,2,4,5,6,7,9}
f) (C∩D) ∩B ={1}
