Hi, Victor>>>
...my intuitive feel is always to favor the higher power.
<<<Though I agree that e^pi > pi^e, the higher power per se
doesn't guarrantee nothing, 2^3 is LESS than 3^2.
My proof is as follows:e^pi ??? pi^e
ln( e^pi ) ??? ln( pi^e )
pi ??? e * ln( pi )
pi - e * ln( pi ) ??? 0
Now let's consider it as the function
f( x ) = x - e * ln( x ) when x = piderivative is
f'( x ) = 1 - e / x,f( x ) minimum is when f'( x ) = 0, when x = e,
min value is
f( e ) = e - e * ln( e ) = 0Well, that means
x - e * ln( x ) > 0, when x not= epi - e * ln( pi ) > 0
pi > e * ln( pi )
ln( e^pi ) > ln( pi^e )
e^pi > pi^e
Hope my deduction is correct. :)
