Ok, i have a test tomorrow for my digital logic class and i had a practice exam and i got it back and didn't do too good on it. I'll post the boolean algebra problems that i got wrong and see if anyone can help

X = A'B'C + A'BC + ABC

X = AB'C + AB + AB'C'

X = (A +B' + C')' +ABC

X = A'B'C + A'BC + ABC

I don't think the answers i got were right. Any help?

What are your answers you speak of? It would be easier to guide you on your errors.

Hawkeye87,

You are in big trouble, dude. #1 is wrong, it should be A'C+BC . #2 should be just A . #3 is BC . #4 is the same problem as #1, and this time is correct.
