Correct answer: B
First, calculate the numerator: 0.05 × 0.05 × 0.05 = 0.000125, and 0.04 × 0.04 × 0.04 = 0.000064. Adding these gives 0.000125 + 0.000064 = 0.000189.
Next, calculate the denominator: 0.05 × 0.05 = 0.0025, 0.05 × 0.04 = 0.002, and 0.04 × 0.04 = 0.0016. So, the denominator is 0.0025 - 0.002 + 0.0016 = 0.0021.
Now divide: 0.000189 / 0.0021 = 0.09.
The value of the expression is 0.09.
