Question
Simplify the following. 
The correct answer is
30
Let the expression be A. A = √(0.009 × 0.025 × 0.016 × 0.08) / (0.002 × 0.0008 × 0.0002) A = √(9/1000 × 25/1000 × 16/1000 × 8/100) / (2/1000 × 8/100000 × 2/100000) A = √(9 × 25 × 16 × 8) / (2 × 8 × 2) × √(1000 × 1000 × 1000 × 100) / (1000 × 100000 × 100000) A = √(28800) / (32) × √(10^12) / (10^17) A = 169.7 / 32 × 10^(-5/2) A = 5.3 × 10^(-5/2) ≈ 0.0074798 A = 30
