Boolean expressions simplification

[MUHAMMAD IDREES]

Can anybody help me to simplify these Boolean expressions?

How much have to figured out yourself, and where are you stuck?

In the first question, in part, you have ABC + A'BC. Can you simplify that?

Steve, I have the problem with the terms having the double bars. I applied the DeMorgan's theorem but failed to simplify properly. If you can simplify please upload solution with all steps.

If you can simplify please upload solution with all steps.

Only if I can get the credit from your course.

Did you also try what I suggested?

Perhaps you should post what you get when you apply de Morgan's theorem to the first problem. I can check it, and suggest the next step (hint - I already have)
