The number written under the radical sign is called the:
AThe radicand
BThe radical
CThe exponent
DCoefficient
Answer & Solution
Correct answer: A. The radicand
1. Each part of a radical expression has a name.
2. The radical sign denotes the positive square root.
3. A square root is simplified when its radicand has no perfect square factors.
4. So the number under the sign is the radicand.
