Cube root can be done with a compass-and-straightedge construction. Newton's method is an iterative method that can be used to calculate the cube root. For real floating-point numbers this method reduces to the following iterative algorithm to produce successively better approximations of the cube root of "a": The method is simply averaging three factors chosen such that at each iteration. Halley's method improves upon this with an algorithm that converges more quickly with each step, albeit consuming more multiplication operations: With either method a poor initial approximation of "x" can give very poor algorithm performance, and coming up with a good initial
Root Creek, Wisconsin Root Creek, Wisconsin Root Creek was a hamlet in Sections 21-22 and 27-28 of the Town of Greenfield in Milwaukee County, Wisconsin, on the Milwaukee-Janesville plank road, at what is now roughly the intersection of that thoroughfare (now Forest Home Avenue) and 68th Street. The body of water after which it was named is nowadays referred to as the Root River. The post office there was established August 19, 1847, near the eastern bank of Root Creek. When Peter Lavies became postmaster in 1854, soon after the establishment of the Hales Corners post office just on the other side of
