    This problem is very interesting.

    but,, I don't know how to solve it... T,T

    "If a<b, what are both ordered pairs of integers (a,b) which

    satisfy a ^b = b ^ a ?"

    Yes, that is a very interesting problem. The first thing I would do is start experimenting with a and b small integers. Have you done that? If so, one of the two pairs should come immediately and the other is not too difficult to find.
