Is there a new way to calculate a number’s cubed root?

Recent news articles from India report that Mr. Nirbhay Singh Nahar has developed an algorithm to calculate the cube root of any number.

Given an equation stating “y = x^3″, Nahar’s method would solve for “x = y^(1/3)” without the need to refine repeated approximations.

In this article, we assume that Mr. Nahar refers to finding the real cubic root of a real number, rather than also finding complex roots.

## A Summary of Nahar’s Claim for a Cubic Root Formula

Apparently Mr. Nahar has obtained a copyright for his formula, “NAHNO” (“NAHar Number”), and is pursuing a patent for it.

According to reports, he wishes to collaborate with one or more well-known mathematicians, presumably to have his work pubished in a respected mathematics journal, and has stated that his overarching aim is for “*the credit for my work to go to India, my country*“. In the meantime, however, he has not released his formula for scrutiny.

## Previous Methods of Calculating a Cubic Root

Several methods already exist for calculating a cubic root, including Newton’s Method for an ‘N’-th Root, Halley’s Method for an ‘N’-th Root, and a Long Division Method for a Cube Root.
