Material Node Power not working as expected

Im having a hell of problems with power node not working as expected. I have made a simple project just to make sure what I was seeing was for real, but images attached will explain it simple:

every value where you power at 1 should return same value… thats not happening… The expected resulting box is on the left, while thats what Im getting on the right :frowning:

nevermind, forgot the negative values… and missed a clamp just after Noise node
