Find Two Natural Numbers a and b such that...

b>a and a^b = b^a

I cant figure this problem out. I tried a = -2 and b = 2 but then realized that Natural Numbers are positive numbers. and that you wouldnt be able to take an exponent to a negative number. How can I figure this out??

Try every pair from 1 to 5 - you'll have 20 pairs. You will find a pair that satisfies the condition
