State the complement law and the idempotent law of Boolean algebra.
Original Khojo Papers practice question — not from a past board paper.
Answer
The complement law states that X + X′ = 1 and X · X′ = 0. The idempotent law states that X + X = X and X · X = X.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
