I'm pretty sure that U(30) = {1,7,11,13,17,19,23,29}. Just the numbers less than 30 that are coprime with 30. | I'm pretty sure that U(30) = {1,7,11,13,17,19,23,29}. Just the numbers less than 30 that are coprime with 30. | ||

Revision as of 18:03, 12 February 2009
To do this one, I followed the example that Uli did in class last Thursday. It follows that and is pretty straightforward. --Podarcze 12:12, 9 February 2009 (UTC)
This might be a dumb question, but I'm a little confused about what {1,11} actually means. I thought it was just the set of the two numbers, but when I looked at the example 1 in chapter 7 I got a little confused. --Clwarner 21:11, 11 February 2009 (UTC)
I wasn't in class last Thursday, can anyone elaborate on the example Podarcze mentioned? --Bcaulkin 22:12, 11 February 2009 (UTC)
Question: I know this is silly but I am still a little confused on the meaning of U(30). Thanks! --Eraymond 12:57, 12 February 2009 (UTC)
