For the first part assume that G has s components. Then as it's forest we have that each such component is a tree and hence if V 1 is the number of vertices in the first component then there are V 1 − 1 edges in it. Obviously the number of edges in G is given by: E = ∑ n = 1 s ( V n − 1) = ∑ n = 1 s V n − s = V − s s ...
