Homework Help: Truth table

  1. Aug 8, 2013 #1
    1. The problem statement, all variables and given/known data

    Hello, I was working on the following truth table problems

    and wanted to know why I got different truth tables it seems that we could use the associative law to rewrite 1. in the same manner as 2.

    Or am I missing something?



    2. Relevant equations

    3. The attempt at a solution
