minimal effort to answer the question for themselves. To do so otherwise is rude
in and of itself because it places a time requirement on others. Even a cursory
web search by the O.P. would have revealed the answer. Teachers should not
have to waste their time with students who are unwilling to do basic homework.
Some additional thoughts:

Suppose that I had asked (in response to the first post)

"What have you done so far that makes you believe what you say? Please
show your work. Also tell us why you might think there is a relation between
FLT and the existence of higher order residues."

Do you believe that such a request on my part would also be rude??

Sometimes in order to teach we need to see what efforts have been made so far so
that we can see where the student has been led astray. When a poster has shown
(historically) an unwillingness to respond to such requests then an admonishment is,
and should be, in order.

I do not wish to see this sub-forum turn into sci.math. For homework help there is
another sub-forum available. There is also a misc.math sub-forum.

That is your opinion, you are entitled to it. We don't have to share it.

Again your opinion, but this time it is wrong. There is no requirement for others to responded. You have no obligation to respond.

There is no "have to" here. You can just stroll by and not involve yourself. If you feel that the OP is acting irresponsibly, you can have less stress by not dealing with their posts.

It requires time to read the question, even if no response is given.

Why do you presume that dealing with their posts is stressful? I call it amusement.
And silence gives an implied consent that troll questions are OK.


If you want to turn this sub-forum into sci.math, I feel sorry for you. A failure to
perform even a little diligence will turn this forum into sci.math. Cranks, trolls,
and people unwilling to learn should go somewhere else. Questions posed
by people who are unwilling to put in an effort should be discouraged.

Yes, this is my opinion.

And there is another valid reasons for not simply answering such questions:

"Give a man a fish and he eats for a day. Teach a man to fish and he eats for a
lifetime".

According to various of your previous posts, you have assessed the OP as being one that doesn't like fish.

Sorry;just proved that 23 is a non-residue of 7919 upto infinite order. This was done with aid of my paper "Euler's generalization of Fermat's theorem ( a further generalization)- Hawaii international conference ,2004.
Verification : pari code -
Is=Mod(17,7919)^7922 = =23

Also is(n)=Mod(17,7919)^n==23
select(is,[1..7922]==23

Try again, please. At least, if you don't test the pieces of code by yourself, you should carefully check that all the parentheses match...

This example is not correct.correct example:
23 is non-residue of 3571 upto infinite order.I leave it to pari experts like Charles to verify.

Er, ah, 23 is a cubic residue mod 3571.

The cube roots of Mod(23,3571) are Mod(34,3571), Mod(35,3571), and Mod(3502,3571).

Hey clueless. You can't even do simple arithmetic. Nor do you bother to study any
math. The result makes you look stupid every time you open your mouth.

Consider any prime q that does NOT divide (3571-1). Take, e.g. q = 11

note that 1148^11 = 23 mod 3571.

23 is an 11'th order residue mod 3571. I think we all safely know (except perhaps you)
that 11 is finite. You should now be asking "what is special about 11?"

If you had bothered to take my earlier hint about cubic residues modulo a prime
that that is 1 mod 6 vs. primes that are -1 mod 6 you might have avoided this
latest erroneous assertion. I will give a further hint: Only 1/3 of the residues
less than p are cubic residues of p when p = 1 mod 6. But when q = -1 mod 6,
they ALL are. Learning WHY is directly tied into Lagrange's Theorem. It is also
tied into the Sylow theorems. [Ask yourself how many subgroups there are of size
(p-1)/3]

Go learn some mathematics. In particular learn Lagrange's Theorem. Learn
Euler's Theorem for quadratic reciprocity. Study its generalization. Learn what
a primitive root is. Read and study the Sylow theorems.

Consider the following:

Prove or disprove:

For prime p,q, x^q = a mod p always has a solution for every a when q does not divide p-1.

Then ask: What happens if q | (p-1)???


Go read and study Nick's excellent introduction [in this forum] to number theory.
I think we all know that you will ignore this advice.

Finally STFU until you can be bothered studying at least some of this subject.
If you want to post mindless numerology go to the misc.math sub-forum or
open your own sub-forum in the blogorrhea.
