Can you make a target number 37 by using five 5s? You can use any math operator as you want. There are at least two different ways.

((5+5)/5)^5 + 5
((5/5)/.5)^5 + 5
(5*.5 + 5)*5 -.5
5/(5 * .5^5) + 5

(where x^y = Math.pow(x, y))

Various others...

Jim, did you solve it yourself? If yes, give us your train of thought, can you?

I solved it myself in the sense that I wrote the program myself. Actually it was written for an earlier problem; I just modified it slightly.

By the way, all these posts saying "solve this" and "now solve this" could really use some better titles. The existing ones are pretty much useless.
