Answer 1

Răspuns:

A={0,1,2,3,4,5,6]

B={0,1,2,3}

C={0,2,4,6,8}

A*intersectat B= {0,1,2,3}

C*intersectat A={0,2,4,6}

B*intersectat C={0,2}

A*intersectat B*intersectat C={0,2}

AUB={0,1,2,3,4,5,6}

BUC={0,1,2,3,4,6,8}

AUC={0,1,2,3,4,5,6,8}

AUBUC={0,1,2,3,4,5,6,8}

A/B={4,5,6}

B/A= Ø

A/C={1,3,5}

C/A={8}

B/C={1,3}

C/B={4,6,8}

(A/B)/C={5}

A/(B/C)={0,2,4,5,6}

(A/B)U(A/C)={1,3,4,5,6}

(B/C)*intersectat(C/A)= Ø

7.

X∩Y={4,6}

XUY={1,2,3,4,5,6}

X/Y={1}

X={4,6,1}

Y={4,6,2,3,5}

8.

A∩B={a,d,e}

AUB={a,b,c,d,e,f,g}

B/A={f,g}

A={a,d,e,b,c}

B={a,d,e,f,g}

9.

MUN={0,2,4,6,8}

M/N={0}

M∩{2,4,6,8}={2,8}

M={0,2,8}

N={4,6,2,8}

10.

a=0

b=7

11.

M=N

x=0 a=3

y=1 b=6
