Log[15] is exact and will remain in that form until an inexact result is requested {Log[15],Log[15.],N[Log[15]]} {log(15),2.70805,2.70805} Exp[%] {15,15.,15.} {Log[2,15], Log[2.,15],Log[2,15.],N[Log[2,15]]} {Log[15]/Log[2], 3.90689, 3.90689, 3.90689} 2^% {15,15.,15.,15.} Bob Hanlon ---- Joe <joealan at mac.com> wrote: > I am very new so please be gentle.
