In article <4qppbr$ns6@tribune.concentric.net> it was written: >What is the mistake here: > > Z Y > Y Y*Z Z >X = X = X 
The mistake is writing a nonassociative operation (exponentiation) without parentheses, which leaves the meaning ambiguous.
Z Y Y Z If X really means (X^Y)^Z, and X really means (X^Z)^Y, then there is no mathematical error in these equations, only notational error.
