Răspuns:

Explicație pas cu pas:

A=[3,4,5]; B=[5,6,7,8]; C=[2,4,8]; K=[1,3,5,7]

A U B = {3, 4, 5, 6, 7, 8]

A U K = {1, 3, 4, 5, 7}

B U C = {2, 4, 5, 6, 7, 8}

C U K = {1, 2, 3, 4, 5, 7, 8}

A ∩ B = {5}

C ∩ B = {8}

B ∩ K = {5, 7}

C ∩ K = ∅

A \ K = {4}

C \ A = {2, 8]

K \ B = {1, 3]

K \ A = {1, 7}
