So I was looking through my quiz and I'm confused on what exactly Normal POS/SOP and canonical POS/SOP is. Also how was I supposed to go about answering #1 correctly? I tried a truth table but didn't know how to do it properly, but I'd like to know how to do it with algebra as well (with explanation please)

1. State if the A'C + ABC' + A'B + AB' = B'C + A'BC is true or false a. False b. True 2. The function F(W, X, Y, Z) = (x +Y)(W + Y + Z')(W + X + Y + Z) is a form of? a. normal POS b. normal SOP C. canonical POS d. canonical SOP e. None 3. The function F(P, Q, R) = PQ+QR + PR + P'Q' +Q'R' + P'R' is a form of? a. normal POS b. normal SOP C. canonical POS d. canonical SOP None e
