by inspection ... 2 and 3 work
not sure about a "formal" solution method
it's all whole numbers, so there are limited solution possibilities
x + y = 5
x^y + y^x = 17
Find x and y

Thanks Scott. By inspection, the ans is quite obvious I think....something like this..
If x is 2 and y is 3, then 17 could be written as 8 + 9
2^3 + 3^2...I think is not a right approach though.
