7. Let F = (x + y)(x + z) + (x + z')(y, + z) + x'y'z, and G = x + (y z). Show that F = G (Hint: Equivalence operator (-) is defined as (a b-aD+ aw) (a) (1 Point) By using the truth tables of F and G. (b) (2 Points) By simplifying F to the minimum number of terms. (c) (2 Point) Draw the logic diagrams of F and G. Compare the total number of logic gates
