Work: Calculate the value of equation 3.9×1.3×15+3.6×2.2+3.3×1.3×3+(3.9×1.3×17+3.6×2.2+3.3×1.3)×9 .
Question type: Mathematical calculation
Solution:
3.9×1.3×15+3.6×2.2+3.3×1.3×3+(3.9×1.3×17+3.6×2.2+3.3×1.3)×9
=3.9×1.3×15+3.6×2.2+3.3×1.3×3+98.4×9
=5.07×15+3.6×2.2+3.3×1.3×3+98.4×9
=76.05+3.6×2.2+3.3×1.3×3+98.4×9
=76.05+7.92+3.3×1.3×3+98.4×9
=76.05+7.92+4.29×3+98.4×9
=76.05+7.92+12.87+98.4×9
=76.05+7.92+12.87+885.6
=83.97+12.87+885.6
=96.84+885.6
=982.44
Answer:3.9×1.3×15+3.6×2.2+3.3×1.3×3+(3.9×1.3×17+3.6×2.2+3.3×1.3)×9=982.44
