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 NewtonRaphson algorithm. Do you want only real roots or do you want the complex ones as well? note: http://mathforum.org/library/drmath/view/65174.html http://www.mathpath.org/Algor/cubero....cube.root.htm ... 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. :)
