Salutare!
[tex]\bf A\cup B = \{1,2,3,4,5,6,7,8\}\:\:\:\:\:\text{\it (relatia 1)}[/tex]
[tex]\bf A\setminus (A\cap B) = \{1,2\}\implies \{1,2\}\subset A \:\:\:\text{\it (relatia 2)}[/tex]
[tex]\bf B\setminus (A\cap B) = \{7,8\}\implies \{7,8\}\subset B \:\:\:\text{\it (relatia 3)}[/tex]
[tex]\text{\it Din relatiile (1), (2), (3) avem:}[/tex]
[tex]\bf A\cap B = \{3,4,5,6\}[/tex]
[tex]\bf A = \{1,2,3,4,5,6\}[/tex]
[tex]\bf B = \{3,4,5,6,7,8\}[/tex]
