Explain the De-Morgan's law?

Answer 1

DeMorgan's law states that the negation of a conjuction is equal to the disjunction of negated terms.

Alternatively, DeMorgan's Law also states the negative of a disjunction is equal to the conjunction of negated terms.

NOT(A and B) = NOT(A) or NOT(B)

NOT(A or B) = NOT(A) and NOT(B)

Answer 2

1.(AUB)'=A'intB'

2.(AintB)'=A'UB'

3.A-(BUC)=(A-B)int(A-C)

4.A-(BintC)=(A-B)U(A-C)
