    The process of finding all real numbers for 3^x+4^x=5^x

    find all real x for
    3^x+4^x=5^x

    So this has been bothering me for awhile. I know that the answer is 2, but I need to know how to get to that point. Can someone please provide the steps needed to solve for all real numbers? Thank you.
