In fact, we think of radicals as reversing the operation of an exponent.
In mathematics, the radical symbol, radical sign, root symbol, radix, or surd is a symbol for the square root or higher-order root of a number. The square root of a number x is written as x , {\displaystyle {\sqrt {x}},}
A solution by radicals of the cubic was first published in 1545 by Girolamo Cardano, in his Ars Magna ( The Great Art, referring to algebra); it was discovered earlier by Scipione del Ferro and by Niccolò Tartaglia.

These are called radical expressions. By the sixteenth century rational numbers and roots of numbers were becoming accepted as numbers although there was still a sharp distinction between these different types of numbers.
