1. The problem statement, all variables and given/known data I am suppose to use Boolean algebra to show that the following expressions are true. 2. Relevant equations w'z' + w'xy + wx'z + wxyz = w'z' + xyz + wx'y'z + wyz 3. The attempt at a solution I have tried to figure out how to get to that answer above but I am stuck and not sure what to do or if I am even doing it right. Here is what I got so far: w'(z + xy) + w(x'z +xyz) w'(z + xy) + wz(x' + xy) w'(z + x' + y') + wz(x' + x' + y') w'(z + x' + y') + wz(x' + y') Thanks!
