Answer 4

lol, it says I am not viewing, but I am.

Answer 5

(pvq) ^ -(p^q) ; distribute the -

(p v q) ^ (-p v -q) ; thats the only one im comfortable with, but we can check things now

the ^ inbetween means true when both cases are true

try f and f
(f v f) ^ (-f v -f)
f ^ t = f

try f and t
(f v t) ^ (-f v -t)
t ^ t = t

try t and f
(t v f) ^ (-t v -f)
t ^ t = t

try t and t
(t v t) ^ (-t v -t)
t ^ f = f

Answer 6
