Need help with a logic expression and truth table

[Shiinobii]

Hey guys, I'm pretty new to this subject and I never use forums so forgive any mistakes. Currently learning about logic expressions and beginning with it and I'm struggling with an expression. I don't really know how to put it into a truth table. and I have another equation in which I have to put into a truth table. I kind of struggle with truth tables... Thanks for any help you can give, all help is appreciated.

Hi Shiinobii,

I've seen your problem.
In the attachment, you'll find the solution for the first problem.

I didn't solve the other problems, for that you'll need the same solution.
Concerning the second problem, you'll have to do the same. There is also an other expression possible.

For the third problem, you can use logiccircuits to build your circuit. Then you can find out the truth-table,
that is belonging to this circuit.

If you don't understand something, you can ask me anytime.

Best Regards
