Using a Calculator to Find Rational Roots

Bert K. Waits

Cited by 0Abstract and details only

Abstract

A recent article in the Mathematics Teacher (Eimer 1977) included a recursive method for finding the cube root of ten that used a square root algorithm. The method required only a simple four-function calculator with a square-root key and a memory. In this note we present a more direct method for approximating the nth root of any positive number that requires only a four-function calculator with a square-root key and repeat multiplication capability.
