A{'text': '0.0035'}
B{'text': '0.35'}
C{'text': '3.5'}
D{'text': '0.035'}
Answer & Solution
Correct answer: D. {'text': '0.035'}
1. Write 0.001225 = 1225 / 1000000.
2. √1225 = 35 (since 35² = 1225).
3. √1000000 = 1000.
4. Therefore √0.001225 = 35 / 1000 = 0.035.
5. Verification: 0.035 × 0.035 = 0.001225 ✓.
6. Hence the answer is **0.035**.
