[edit] The Nth.Root and the Root-Solving History
It is certainly disturbing to realize that the extremely simple high-order arithmetical methods for approximating the Nth. root shown at: Arithmetical High-Order root-solving methods do not appear in any book on numbers since ancient times up to now, of course, including the wikipedia whose root-solving experts also seem unaware of these trivial high-order methods. Believe it or not.
[edit] .
"Quantities left uncomputed under a radical sign are also called surds." This is not correct. Surds are strictly irrationals.
This article talks about "surds" before defining what they are. - dcljr 06:03, 6 Aug 2004 (UTC)
This article also perports to define the term radical, and at no point does it directly do so.
The section, 'Finding all the roots', tells us how to find all the roots in terms of the principle root and n, but the only definition for the princinple root used in the article is the one which is always a real number and doesn't always exist. Someone needs to put in a bit about the extension to complex numbers. There is actual more on the cube root page.
Cool, thanks.

I think this article and N-th root are the same thing, just under different names!

shouldn't the equation for finding the nth root be on this page?? 'twould be useful to say the least (not to mention relevant) x(1 / n) = e((lnx) / n)
