Let

be a natural number such that
is a perfect square. Try then
is the sum of two squares. Are they straight?

I did this:


and as I now? dunno

I know that I use but not as.

Help me!

I have a question.
In what year of school or college learned that?

yikes

I go to sleep. Tomorrow partial geometry.

I hope not to have a blank mind big_smile

I think you miss something. Tell me if I'm wrong.

Says they have to be the 4 boxes full.

It means that the combination 000000|00|00| not allowed since the fourth box would be empty.
I would have to subtract these possible ways taking it to 000000|00|00 being "|" missing one of the stops.
And also when it is of the form 00000000|00||  and form 0000000000||| .
As would be empty boxes.

Hi.
You would have to first find the diameter of the coins and the area.

I don´t have any formula. Sorry

I search the internet but only found up to 1,000,000

So I ask the other using the algoritme because I feel that I have numbers larger than 3,000,000

Hello forum members.

I come with an enthusiasm to solve the mystery of prime numbers ...
Is there any algorithm to calculate them all? dunno

I discovered an algorithm 2 days ago when I was bathing. But not as a check. what
Also I have to show that they all prime numbers.
It is based on the selection of two numbers (that which must be defined) and enter the algorithm that results in a prime number.
For now is working. (Not a computer program, only one account)

I wanted to know if anyone would have the prime numbers from 1,000,000 to 100,000,000 would not have to see if the result is prime or not. (I have the numbers to 1,000,000)

I do not own any advanced technology to calculate them.

Of course, thank you very much. up
