Examples of radicand in the following topics:

  • Imaginary Numbers

    • When the radicand (the value under the radical sign) is negative, the root of that value is said to be an imaginary number.

  • Fractions Involving Radicals

    • Recall that a radical multiplied by itself equals its radicand, or the value under the radical sign.

  • Domains of Rational and Radical Functions

    • To determine the domain of a radical function algebraically, find the values of $x$ for which the radicand is nonnegative (set it equal to $\geq 0$) and then solve for $x$.  
    • The radicand is the number or expression underneath the radical sign.  
    • Set the radicand greater than or equal to zero and solve for $x$ to find the restrictions on the domain:

  • Adding, Subtracting, and Multiplying Radical Expressions

    • To add radicals, the radicand (the number that is under the radical) must be the same for each radical, so, a generic equation will have the form:

  • Simplifying Radical Expressions

    • there is no factor of the radicand that can be written as a power greater than or equal to the index,
