When I try to run your code, I get an incorrect answer for the root. I think the problem is in the exponent. The exponents are $root and ($root - 1), respectively.

When I run this code:
timethese( 100, { 'Root' => '$x = Root( 100, 3 )', 'Root2' => '$y = Root2( 100, 3 )', }); print <<END; Root: $x ----- Root2: $y END
I get this for output:
Benchmark: timing 100 iterations of Root, Root2... Root: 29 wallclock secs (28.39 usr + 0.00 sys = 28.39 CPU) @ 3 +.52/s (n=1 00) Root2: 20 wallclock secs (20.03 usr + 0.00 sys = 20.03 CPU) @ 4 +.99/s (n=1 00) Root: 4.6415888336127788924100763542328778501807372125002714 ----- Root2: 0.6664902595019951166742874561807256134735
