Question: 2. Weak Induction (15 points) (1) (5 points) Using weak induction, prove that 3 6. (2) (5 points) Prove that log(n!) 1. Reminder 1: log(1)

2. Weak Induction (15 points) (1) (5 points) Using weak induction, prove that 3" 6. (2) (5 points) Prove that log(n!) 1. Reminder 1: log(1) = 0. Reminder 2: log(a*b) = log(a) + log (6). Reminder 3: If a 1 that if A1, A2, ..., An and B are sets, then: (ANA2N...NAn)UB = (AjUB)n(A2UB)N...N(AUB) Hint: Use the fact that (XNY) UZ = (XUZ)n(Y UZ) where X, Y, and Z are sets.
