Explanation

Step 1: Calculate denominator without 10⁴
27.5 × 3.2 = 88

Step 2: Include 10⁴
Denominator = 88 × 10⁴ = 880,000

Step 3: Perform division
3476 ÷ 880,000 = 0.003950…

Step 4: Round to 4 decimal places
= 0.0040

Step 5: Note on answer format
0.0040 shows exactly 4 decimal places
0.0039 would be rounding down
3.95 × 10⁻³ = 0.00395 (5 decimal places when written)
Answer needs trailing zero to show 4 decimal places: 0.0040
