Question

Calculați.a){2,3,5,5,7}intersectat {0,6,4,8};b){1,3,5,7,9}\{1,2,3,4,5,6,7,8,9};c){3,4,5}intersectat {7,8,9,10}.

Answer 1

a)   {2;3;5} n {0;6;4;8} = $\phi$ 
b)   {1;3;5;7;9} \ {1;2;3;4;5;6;7;8;9 } = $\phi$
c)    {3;4;5} n {7;8;9;10} = $\phi$

Answer 2

(2,3,5,5,7)n(0,6,4,8)= multimea vida
(1,3,5,7,9,)-(1,2,3,4,5,6,7,8,9,)=multimea vida
(3,4,5)n(7,8,9,10)=multimea vida
