Numerical algorithm of the n-th root

摘要

Currently, in order to square root for each single digit of a given positive real root is a direct analysis method are available. Also, to compute the n th root of a given positive real number, it is possible to use the trial and error method, iterative method. When determining the n-th root, in such a way, for example, or it is necessary to guess initially, they involve enormous arithmetic, and or it is necessary to converge by performing multiple iterative steps, each I know that there inherent disadvantages are several. Direct method to determine the n-th root of a given positive real number did not exist before. The present invention is focused on the development of numerical algorithms to square root of n-th root of a given positive real number for each one digit in any desired accuracy. In some examples, to illustrate this algorithm. .
