Hello Friends,
I have a question of calculating a cube root of large number like 24 digit number.
I calculated by means of Wolfram but I want to try it myself on paper. Is there a method such as Calculus or Algebraic to find the cube root?
Thank you.
P.S. I want to use the method for several other numbers.

Factorize the number into simpler roots and multiply them.
Solve for the prime numbers using the Newton-Raphson algorithm.

Do you want only real roots or do you want the complex ones as well?

... note: this last one is probably what you want.

Well the number is : x^3= 133737775549834923406792. So I wish to find out the 'x'.
And x is a positive integer. So I only want the real part here. And the real part only exists.
thanks Simon Bridge. :)

You can try an algorithm like this: http://www.mathpath.org/Algor/cubero....cube.root.htm
