@thetechie , welcome to daniweb :)

regarding the problem above , have you tried writing some code? or do you want some algorithm of sorts? if you have some code, you can post it here , it would help the members to help you...

to answer your question , try using this method :

r^n = x.
therefore , ln r = ( ln x )/n
therefore , r = exp ((ln x)/n)

where : x = number , r = nth root.
hope it helps.
