Secondly I have been stumped on this for days now and I only have one more attempt at this homework assignment and I would like to get these two correct but I can not for the life on me find this in the text book or online somewhere on how I do these two problems I have searched everywhere and cant figure out how to do these two.

lastly I linked each of the two problems in imgur so its a bit easier to read.

First question is: For this one I tried using different properties in the text book but i have not gotten it right a single time so maybe i'm just not doing it right i'm not sure.

Second question is: For this one I tried making a truth table twice and maybe I did not construct it correctly either time?

Thank you for any help you can offer I feel defeated with these two problems and I cant seem to find help for this in my textbook or oneline.
