Root Extraction from a Number

Root Extraction of Degree n from a number x equals the value of raising that number to the power of 1/n. Such a definition of the root was generally given in the 14th century by Nicholas Oresme.

The root is a mathematical definition known since Sumerian times. In Egyptian writings, it was denoted by a special sign. On papyri from the time of the construction of the Pyramid of Khufu, tables of square roots important for performing various practical calculations were found.

In the direction of studying and extracting roots, ancient scholars worked (Aryabhata and others.) and medieval mathematicians (Khayyam, al-Kashi, Stifel, Euler, and others.). The study of the issue led to the discovery of complex numbers.

No less than in ancient times, root extraction is used in the calculations of modern mathematicians, engineers, designers, astronomers, and other representatives of various scientific and practical fields.
