cube problem





akshar
sum of two squares is a third square we call it pythagorian triplet.

But does there exists a triplet such that sum of 2 cubes is equal to third? I raise this question because it is impossible to get a third large cube by joining two cubes of integral edge.

So, you said that:
Code:
a^2+b^2=c^2

is a pythagorian triplet, and you're right. And you want to ask if there are any a, b, c real numbers which fulfill the following equation:
Code:
a^n+b^n=c^n

where n>2.
The answer is NO. This is called the Fermat theorem (do a search for it), and it has been proven in the near past.
I hope you are satisfied now.

Thank you very much. I searched the theorem on wikipedia and got good insight of it
