যদি √(0.04 × 0.4 × a) = 0.4 × 0.04 × √b হয়, তবে a/b এর মান কত?
Solution
Correct Answer: Option D
√(0.04 × 0.4 × a) = 0.4 × 0.04 × √b
∴ 0.04 × 0.4 × a = 0.4 × 0.4 × 0.04 × 0.04 × b
⇒ a/b = 0.4 × 0.04
সুতরাং, a/b = 0.016
∴ 0.04 × 0.4 × a = 0.4 × 0.4 × 0.04 × 0.04 × b
⇒ a/b = 0.4 × 0.04
সুতরাং, a/b = 0.016
