[xvxqfxbe] log(x)^e

below are some values of the function ln(x)^e mentioned in passing in what if?  ("it's hard to imagine a situation where it would apply").

(future post xvvojqgz: a family of sublinear functions which includes log(x)^a .)

log(15)^e ~= 15 is interesting.  exact root is at e^e=15.15 (incidentally, cannot be solved by Mathematica).  e^e is also one of the two places where the derivative (e*log(x)^(e-1))/x is equal to 1.  the other place is at e.

the function is undefined (not real) for x<1, is 0 at x=1, and is concave up until x=e^(e-1) ~= 5.6 .  beyond that it is concave down, looking like logarithm stretched vertically.

? for(x=1,100,print(x," ",log(x)^exp(1)))
