Question 1: http://imgur.com/Px0n152 Question 2: http://imgur.com/tZ0beF6 For Question 1, I got: (AB.CD) + [(CD)' . (AB)'] with a "." = multiplication and ' = complement. into (AB.CD) + [(CD+AB)'] I"m not sure how to simplify this further. Question 2 is really long and I would appreciate help. I got: A' + (D'+C') + A + (A' + C'+ D') + B' .D ' + (D+B)' = F I'm not even sure if this is correct, and these two questions are due as homework tonight. Any help would be much appreciated, thank you.
