WebA radical is a symbol used to denote the root of a number. It is represented as √. And the term or expression written below the radical sign is called the radicand. So, it can be said that radical is the symbol of the radicand. In other words, the radicand symbol is √. There is one more term associated with the radicand which is called index.

WebIn this expression, the symbol is known as the "radical," and the solution of 7 is called the "root." Finding the value for a particular root can be much more difficult than solving an exponential expression. For now, it is important simplify to recognize the relationship between roots and exponents: if a root
WebFor a denominator containing the sum or difference of a rational and an irrational term, multiply the numerator and denominator by the conjugate of the denominator, which is found by changing the sign of the radical portion of the denominator.
