Brilliant, thanks! I was trying negative no's and using Y as -2 to evaluate all alternatives!
x, y are non zero integers: Is x^y < y^x
(2) x and y are consecutive integers
What's the fastest method to solve this problem?
I'd say number plugging.
For (1)+(2) if x=1 and y=2, then the answer is YES but if x=3 and y=4, then the answer is NO. Not sufficient.
