There will be at least one problem from this material included in the test next Friday, so make sure you are doing the homework. I will talk about the test on Wednesday to give you an idea what to review for Friday. My 'observation" in class was actually #26 on page 178. Do ## 27,28,29,30,31,32 on page 178. Do ## 42,43,45 on page 181. Do ## 46,48 on page 181, also try to do ## 51,52,53,54 on pages 181-182, at the very least read them and understand what the statements mean. This is the complete homework for this week. I will describe the structure of the Friday test on Wednesday. 1) Here is a solution of the problem I promised to post today. 2) To clarify the answers I was giving regarding the Euler's Theorem on the test: since we have just learned this theorem, all I want you to know for the test is the statement of Euler's Theorem and how to use the homework problems #51 through #54 to compute the value of the Euler function when you can factor your modulus m into primes.
