Math 311, quiz 2: state the binomial theorem. Answer:the binomial theorem says that for any positive integer n, and any real number x, (1 + x)n = n. Answer: two numbers are relatively prime when there is no integer greater than 1 that evenly divides both: prove that for all positive integers n, 3|5n 2n. Answer: i will prove this to you using regular induction. If n = 1, then 5n 2n = 5 2 = 3 and 3|3, so for our base case, if n = 1, then 3|5n 2n. Now, let"s assume for some integer k, 3|5k 2k. = 3(5k) + 2(5k 2k). from the de nition of divisibility, 3|3.
