. 6. (a) Use mathematical induction to show that for all n 21, (7 points) ) + 2)2 +63)3 + 3) = 1 (3)", 121. n> (b) Provide a direct proof of the following result. (8 points) 1* (1!) + 2 * (2!) + 3* (3!) + ... +n* (n!) = (n + 1)! - 1. = (Hint. Write 1* (1!) = (2 - 1) * (1!) = 2! – 1! 2 * (2!) = (3-1) * (2!) = 3! – 2! 3* (3!) = (4 - 1) * (3!= 4! – 3! etc.)
