1. (A' ^ B')'
2. (A')' v (B')' 1, DM ?

OR

1. (A' ^ B')'
2. A v B 1, DM ?

yes. (A')' = A

(A' ^ B')' = (A')' v (B')'

is correct. Same with the second.

DeMorgan: (A v B)' = A' ^ B', (A ^ B)' = A' v B'
(the other thing is A v A' <=> w resp. B ^ B' <=> f)

(all the while assuming with ' you mean "not"..)

That's what I thought, but it seems as if the second method is off. Atleast that's what my friend told me not to do on the mid-term, unable to explain why.

thanks =]

well, if unsure, just make a table.
having that, you go on with calculating (A' ^ B')' and A v B and you see it's the same!

BTW: your two 2. are basically the same because (A')' = A (not not = nothing)

10 = 2 in binary
Thus he means that there is 2 type of people in world, one that can read binary, the other that cannot.
