Problem 3. (20 pts) (a) (10 pts) Show that the following equality holds: 12 +22 +32 + + (n - 1)2 + n2 Vn E N, Hint: If you proceed by induction, you might want to use Theorem 1.8.2. If you search for a combinatorial proof, consider the set X = { (i, j, k) : 0 i, j < k n). (b) (10 pts) Prove the following formula: Hint: As above, if you proceed by induction, you might want to use Theorem 1.8.2. If you want a combinatorial proof, you might want to consider the set
