Is there any "pencil and paper" method to find the nth root of a number?(adsbygoogle = window.adsbygoogle || []).push({});

Since multiplying a number by itself any number of times quickly yeilds extremely large numbers, trial and error might seem to pinpoint the root of a number, so long as it is a perfect square or cube or whatever.

But, is there any real way to pinpoint the root of a number without using a calculator or trial and error?
