In Identity Law A . 0 = 0

(A' = NOT A)

Accordingly, which of the statement is another example to Identity law?

• A + A = A

• A + B = B + A

• A + 1 = 1

• A . B = B . A

In Idempotency Law A + A = A

(A' = NOT A)

Accordingly, which of the statement is another example to Idempotency law?

• A . A = A

• A + B = B + A

• A + 0 = A

• A . B = B . A

In Complement Law A + A' = 1

(A' = NOT A)

Accordingly, which of the statement is another example to Complement law?

• A . A' = 0

• A + A' = A

• A + 0 = A

• A . B = B . A

In Commutative Law A + B = B + A

(A' = NOT A, B' = NOT B)

Accordingly, which of the statement is another example to Commutative law?

• A . A' = 0

• A + A' = A

• A + 0 = A

• A . B = B . A

In DeMorgan’s Law (A+B)' = A' . B'

(A' = NOT A , B' = NOT B)

Accordingly, which of the statement is another example to DeMorgan’s law?

• A . A' = 0

• A + A' = A

• (AB)' = A' + B'

• A . B = B . A
