A little problem

  1. May 25, 2005 #1
    Here is the question: "could you fine n>2 (n natural number) so that: a^n+ b^n=c^n with a, b and c real numbers".

    I have got an idea but I am not sure if it works.

    Thank you very much

    Sure, no problem. Take n = 3 and a = 1, b = 2 and c = 3^(2/3)...

    There are none for integers a,b, and c.

    yep it is fermat's theorem...ok thank you!

    But what you posted isn't Fermat's Last Theorem. For real a,b and c, there are an infinite number of solutions for every natural number value of n.

    He just neglected to mention the integer requirement, which I amended.

    No he didn't neglect anything, he said "with a, b and c real numbers".

    How is that not neglecting to mention the integer requirement.

    The Real Number set is an entirely different number set to the Integers. The poster said Real Numbers.

    The issue here is of word choice. I said "neglecting to mention the integer requirement" is the same as "not mentioning the integer requirement".

    He mentioned a problem very similar to FLT in which I referenced him to the correct form. It turns out that is what he is looking for.
