Question

Ex 3! Cu rezolvare va rog

Answer 1

Răspuns:

a reunit cu b {0,1,2,3,4,5,6} ; b reunit cu a {0,1,2,3,4,5,6} ; a intersectat cu b {2} ; (a reunit cu b ) = {1,2,3,4,5,6} reunit cu c = {1,2,3,4,5,6,7,8,9} ;

b reunit cu c ={ 0,1,2,3,4,6,7,8,9} reunit cu a = {1,2,3,4,5,6,7,8,9} ;b intersectat cu a = {2} ; a/b = {1,3,5} ; b/a = {0,4,6} ; a/b ={1,3,5}/c = {2,5} ; a/(b/c) = b/c= {0,2,4} /a ={0,4}

Answer 2

Răspuns:

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

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

AVB={2}

(AUB)UC={1,2,3,4,5,6,7,8,9}

AU(BUC)={0,1,2,3,4,5,6,7,8,9}

BVA={2}

A\B={1,3,5}

B\A={0,4,6}

(A\B)\C={5}

A\(B\C)={1,3,5}
