Hi;

A computer search for integers -40 <= a,b,c, <=60 did not find any answers of the form

I can widen the search using a pslq but I think you want small constants as your examples suggest.

Hi;

I am sorry, try http://www.mathisfunforum.com/viewtopic … 00#p198900

Hi;

Is there an alternate option?

Please let me speak to you frankly and honestly. The problem is this, I have to protect the account of Mathegocart. It is not possible to just hand over his password. It is a severe breach of security. I know him and like him and he is a member here, I can not be sure whom I am posting to right now. You could be someone trying to compromise his account. The only proof of your identity is that you know his email address. I am afraid that is not enough.

Here is what I will suggest, create a new account as mathgogocartincognito and post as before. After a while as I become convinced that you are him I will transfer the post count over to the new account and change the name if you want.

Please understand why that is what I must do. The rights and privacy of members especially the children is number one.

If you are Mathegocart, I urge you to please accept my solution. If you are not and are just trying to trick me into allowing you access to his account, I will hunt you down.

Did you try using the link to retrieve your password?

On the Login page at the bottom and on the right you will see the Forgotten your password link?

Just hit the link " Forgotten your password?" and you can get a new password.

Hi;

You do not remember your password?

Hi;

This is a bit rough but it will find solutions by inspection.

We say

where m >=0. Solving for n

by inspection we need an m that m - 20 is a square and m is a square. That immediately gives m = 36 and n = 4 and n = 28 those are the first two answers.

Of course you can get two more answers using m = 20 which yields n = 8. and m = 0 yields n = - 2

I leave to you the proof that these are the only 4 solutions.

Could be my imagination.

Hi;

I am getting 43/5 for the mean (without switching) the answer I am getting is the same as yours.

Hi;

Remember the Cipolla formula has a much wider range, it must handle from 1 to infinity as best it can. The polynomial is expected to be better in the small range we fit for.

I have never met Sneha. I see that you have discovered girls who need math help. Very good! Is this her?

When I was bit younger I would head to the UNLV library early in the morning during exam time. I would pile up math books on a nice table that was strategically located near the entrance. Then the gals would pile in, all of them nervous about exams. Soon one would saunter over and ask for math help. Better than any singles bar that Vegas had or has.

The handwriting is not so clear to me. Can you write it up a bit better.

Your picture looks a bit thin.
