expm1(3p): Mathematical error in given example

  Hi there!

In the APPLICATION USAGE section of expm1(3p)[1] the given example is wrong:

===8<=== Snip =========================================

[..] calculations of ((1+x)n-1)/x, namely:

           expm1(n * log1p(x))/x

======== Snap ====================================>8===

Actually, both expressions are not equal, rather

 expm1(n * log1p(x))/x = ((1+x)**n - 1)/x

(with a fictional ** as power infix-operator) would be.


  Best regards
