Easy -1.8 This is a direct recall question worth only 1 mark, asking for a standard formula about complete bipartite graphs. It requires no calculation or problem-solving—students either know that K_{m,n} has mn edges or they don't. Even for Further Maths, this is a trivial bookwork question.
Find an expression for the number of edges in the complete bipartite graph, \(K_{m,n}\)
Circle your answer.
