Upload your detailed work: Q1: Prove (AORB)=AB+AB; Note: by definition : A XOR B=AB+AB, where A is inverse (complement) of A Q2: Derive a simplified Boolean expression (SOP form) for: ( A XOR B XOR C) = ? where A, B, C are Boolean (Binary) variables. Q3: Derive a simplified Boolean expression (POS form) for : ( A XOR B XOR C ) =? Q4: Use K-Map to find SOP expression for a 4 Variable XOR i.e A XOR B XOR C XOR D =
