[link\|http://www.ee.surrey.ac.uk/Projects/Labview/minimisation/karnaugh.html\|Karnaugh map]. It's a two dimensional representation of a truth table. The "sum of products" form is the easiest for filling out Karnaugh maps. Using your first expression but ignoring the outer negation: `a' a b' 0 1 b 1 1` negating flips all bits `a' a b' 1 0 b 0 0` So, indeed it's a'b'.
