Question

Dados os conjuntos A= {a,b,c,d}, B={b,c,d,e} e C={c,e,f}, determine:

a) ( A U B) n C
b) (A U B) n ( B U C)
c) A n B n C
d) A U B U C

Answer 1

a)

AUB= (a,b,c,d,e)n(c,e,f)= (c,e)


b)

AUB= (a,b,c,d,e)

BUC= (b,c,d,e) U (c,e,f)= (b,c,d,e,f)

(a,b,c,d,e) n ( b,c,d,e,f)= ( b,c,d,e)


c)

A= (a,b,c,d)n B=(b,c,d,e)n C=(c,e,f)
_______(b,c,d) ______n (c,e,f)
______________(c)


d)

AUBUC=(a,b,c,d,e,f)
