Explicație pas cu pas:
continuare la ex.10 din atașament:
a) (A ∪ B) \ C = {-6,-5,-3,-2,-1,0,1,2,3,4,6,7} \ {-4,-3,0,5,12,21,45} =
= {-6,-5,-2,-1,1,2,3,4,6,7}
b) (D ∩ B) ∪ (D ∩ A) = {0,2,3,4} ∪ {1,2,3} = {0,1,2,3,4}
c) (A ∩ N) ∩ D = {1,2,3,6} ∩ {0,1,2,3,4} = {1,2,3}
d) (A \ N) ∩ C = {-6,-3,-2,-1} ∩ {-4,-3,0,5,12,21,45} = {-3}
