Question

Dados os conjuntos A= {0,1,2,3,4} , B={1,2,3,4,5,6} e C={3,4,5,6}, determine:
a)A U B=
b)A - C=
c)B U C=
d)A U B U C=
e)A - B=

Answer 1

A U B = {0,1,2,3,4,5,6}
A - C = {0,1,2}
B U C= {1,2,3,4,5,6}
A U B U C = {0,1,2,3,4,5,6}
A - B = {0}

Answer 2

A) (0,1,2,3,4,5,6)
B) (0,1,2)
C) (1,2,3,4,5,6)
D) (0,1,2,3,4,5,6)
E) (0)
