請問(d)畫線地方是怎麼變的 用的什麼集合論定律？

U (0 DU00B)
d) Ā U BU CAOBOC)
Lal An (B-A)-An (BĀ) = BOIAA) - BOO = Ø
(b) (AB) UCABA CODUCĀB)
= (AOBU (Ā OB) Absorption Law
= (AVĀ), B = UnB - B
(C) (A-B) U CAOB)= (A BUCAOB) = AO (BUB) = AO U = A
dĀ UBU CAOBOC)= (AOBULAB) 07]
= [[ABU CAO B)]n[LADB) U C] = (AO BUT = ĀU BUC
