Radicand
Identify the radicand as the expression under the radical sign. Understand how the radicand's value determines whether a root is real or imaginary in Grade 9.
Key Concepts
Property In the expression $$ \sqrt[n]{d} $$, $$d$$ is the radicand and $$n$$ is the index number. Explanation The radicand is simply the number or expression chilling out inside the radical symbol's house. It is the 'stuff' you are taking the root of. Don't overthink it—if it's under the radical roof, it is the radicand! Examples In $$ \sqrt{150} $$, the radicand is 150. In $$ \sqrt{48x^5} $$, the radicand is $$ 48x^5 $$. In $$ \sqrt{\frac{7}{3}} $$, the radicand is $$ \frac{7}{3} $$.
