Hi everybody.
first of all sorry for my bad english :( I have some excercises which i'm stuck in. The first one is:

EX1:
pos.PNG
It asks me to find the POS synthesis (the correct one is the C) First of all i wrote (X0'X2')+(X2X3'X1') then i tried with DeMorgan and i got (X0+X2)(X2'+X3+X1) And now the only thing i thought it was good to do is to multiply all that variables, by doing that im getting again a SOP synthesis. What can i do?

EX2:

In this one i have the logical function (100- -100 10-0 101-) and he's asking me to find the minimum synthesis POS I tried to make a true table considering all of thos '-' as 1s. I tried to focus on the 0s (to get a POS) but nothing

EX3:
d3.PNG
Is this case he's asking me to find the logical function I did the true table from it and tried something with QmC but like even "1100" doesn't give me a 1 in my table
Sorry for all the words and these excercises, i hope someone can help me! :)
Thanks
