Strange behavior of Simplify

I've just run across the following strange behavior of Simplify. (Using Mathematica 4.1.5, Mac OS X). These first two commands work as expected: Simplify[Exp[2*n*(Log[1 + t] - Log[1 - t])]] (1 - t)^(-2*n) (1 + t)^(2*n) Simplify[Exp[n^2*(Log[1 + t] - Log[1 - t])]] (1 - t)^(-n^2) (1 + t)^(n^2) But Simplify refuses to do anything with this: Simplify[Exp[2*n^2*(Log[1 + t] - Log[1 - t])]] Exp[2*n^2*(Log[1 + t] - Log[1 - t])] Can anyone shed some light here? By the way, FullSimplify does the same thing. ----- Selwyn Hollis http://www.math.armstrong.edu/faculty/hollis
