A radicand, in math, is an expression or any number or variable written inside a root symbol. It is the quantity of which we are finding the root. The term "radicand" is used when we learn about exponents and roots. So the value of radicand in √2 is 2. Some examples of radicand are given below: 3 √ (pq) → pq is the radicand.
