I'm arguing with my teacher because she has a different answer from me, and I was able to prove to her with the truth table that I was correct. She's still saying that I did it wrong and there's no way to draw the truth table with DeMorgan's Law. Can somebody solve this problem so I can see what answer you get.

My Answer: [attachmentid=1017]

Teacher's answer: [attachmentid=1018]

What my teacher did was that on the first step she break the long bar into the addition and into the multiplication.

[attachmentid=1020]
