1. Let m be a nonnegative integer, and n a positive integer. Using the division algorithm we can write m=qn+r, with 0 <r<n-1. As in class define (m,n) = {mc+ny: I,Y E Z} and S(..r) = {nu+ru: UV E Z}. Prove that (m,n) = S(n,r). (Remark: If we add to the definition of ged that gedan, 0) = god(0, n) = n, then this proves that ged(m, n) = ged(n,r). This result leads to a fast algorithm for computing ged(m,...

Let S(n) be a statement parameterized by a positive integer n. Consider a proof that uses strong induction to prove that for all n 4.S(n) is true. The base case proves that S(4), S(5), S(6), S(7), and S(8) are all true. Select the correct expressions to complete the statement of what is assumed and proven in the inductive step. Supposed that for k> (1?),s() is true for everyj in the range 4 through k. Then we will show that (22)...

use proof by induction
Day 1. Consider the inequality n 10000n. Assume the goal is to prove that inequality is true for all positive integers n. A common mistake is to think that checking the inequality for numerous cases is enough to prove that statement is true in every case. First, verify that the inequality holds for n-1,2,-.- ,10. Next, analyze the inequality; is there a positive integer n such that the inequality n 10000n is not true!
