My solution agrees exactly with the one posted 'Original'ly by Oskar.  (In fact, I had even used the letter 'k' as the variable in my exponents, also!  It is important of course to note that k must be a non-negative integer.)

It is interesting to see the other solutions that you have found, Dennis.  My question is this; how did you ever find the second set of numbers that you listed?  Did you write a program?

Good puzzle, Mr. Sengupta - thank you!
