Square roots that do not appear to have like radicals may reveal them after:
AAdding the radicands
BReversing the signs
CSimplifying the roots
DSquaring both sides
Answer & Solution
Correct answer: C. Simplifying the roots
1. Two radicals can match even when they look different at first.
2. Adding or subtracting square roots requires like radicals.
3. Sometimes roots do not appear to have like radicals.
4. We find like radicals after simplifying the square roots.
