Question

U = {1,2,3,4,5,6,7,8,9}
A = {1,2,3}
B = {1,2,3,4,5}
C = {2,4,6,7,8} Calcule
a) A U C=
b) B U C=
c) A U B=
d) A n C=
e) A - C​ ​=​

Answer 1

Explicação passo-a-passo:

U = {1,2,3,4,5,6,7,8,9}

A = {1,2,3}

B = {1,2,3,4,5}

C = {2,4,6,7,8}

a) A U C=((1,2,3,4,6,7,8)

b) B U C=1,2,3,4,5,6,7,8)

c) A U B=(1,2,3,4,5)

d) A n C=(2)

e) A - C =(1,3)
