Computer Architecture - Truth Table

Use the truth table to prove that: i- [(X Y)+Z'(X+ZX)]_L = [XY + X'Z'+XY]_L insert your answers in the following table: The inserted values are either logic 0' or 1. ii- [XZ + Y'Z + X Y+X'Y]_L = [X Y Z + X Y]_L insert your answers in the following table: (The inserted values are either logic 0' or 1). iii- [(X'Y') + (R'S) + (XY) + (RS')]_L = [(R' S')+ (X Y)']_L insert your answers in the following table: The inserted values are either logic 0' or T
