I got a different question for you.

Find a number such that,

$\displaystyle \phi(n)=31^2$ - Jan 2nd 2007, 11:42 AMJenny20
hi perfecthacker,

Please do teach me. I do not know how to get it backward for the n.

If you ask me what is phi(6912) , then I can easily tell you that is 2304. But if you give me an answer and ask me to get back to n, i have no idea how to get it. :( - Jan 2nd 2007, 01:28 PMThePerfectHacker
