b) (A∩B) U (A∩C)
c) (A-B) U (A-C)
d) (A-B) ∩ (A-C)
e) (A-B) - (A-C)
f) (B-A) - (C-A)
g) (AUB) - (AUC)
h) (A∩B) - (A∩C)

Answer 1

A∩[B∪C=(3,4,5,6)]=(3,4)

[A∩B=(∅)]∪[A∩C=(3,4)]=(3,4)

[A-B=(2,3,4)]∪[A-C=(2)]=(2,3,4)

[A-B=(2,3,4)]∩[A-C=(2)]=(2)

[A-B=(2,3,4)]-[A-C=(2)]=(3,4)

[B-A=(5,6)]-[C-A=(∅)]=(5,6)

[A∪B=(2,3,4,5,6)]-[A∪C=(2,3,4)]=(5,6)

[A∩B=(∅)]-[A∩C=(3,4)]=(∅)
