Work: Calculate the value of equation 3.9×15+3.6+3.3×3+(3.9×17+3.6+3.3)×9 .
Question type: Mathematical calculation
Solution:
3.9×15+3.6+3.3×3+(3.9×17+3.6+3.3)×9
=3.9×15+3.6+3.3×3+73.2×9
=58.5+3.6+3.3×3+73.2×9
=58.5+3.6+9.9+73.2×9
=58.5+3.6+9.9+658.8
=62.1+9.9+658.8
=72+658.8
=730.8
Answer:3.9×15+3.6+3.3×3+(3.9×17+3.6+3.3)×9=730.8
