যদি√(0.04×0.4×a) = 0.4×0.04×√b হয় তবে a/b= কত?
Solution
Correct Answer: Option B
0.04 × 0.4 × a = (0.4 × 0.04 × √b)²
বা, 0.04 × 0.4 × a = 0.4² × 0.04² × b
বা, a = 0.4 × 0.04 × b
বা, a/b = 0.4 × 0.04
বা, a/b = 0.016
বা, 0.04 × 0.4 × a = 0.4² × 0.04² × b
বা, a = 0.4 × 0.04 × b
বা, a/b = 0.4 × 0.04
বা, a/b = 0.016
