Checking whether the radicand is a perfect square first can save work because it may make the root:
AImpossible to compute
BNegative in value
CLarger than before
DExact with no radical
Answer & Solution
Correct answer: D. Exact with no radical
1. The first check can end the problem immediately.
2. Whenever you simplify a square root, first determine whether the radicand is a perfect square.
3. If it is, the root is a whole number.
4. No radical sign is then needed in the answer.
5. Otherwise the Product Property removes any perfect square factors instead.
