Work: Calculate the value of equation 3.9×1.3×24+3.6×2.2×2+3.3×1.3×3+(3.9×1.3×17+3.6×2.2+3.3×1.3)×9+2.2×1.8×2+1.28×8.2 .
Question type: Mathematical calculation
Solution:
3.9×1.3×24+3.6×2.2×2+3.3×1.3×3+(3.9×1.3×17+3.6×2.2+3.3×1.3)×9+2.2×1.8×2+1.28×8.2
=3.9×1.3×24+3.6×2.2×2+3.3×1.3×3+98.4×9+2.2×1.8×2+1.28×8.2
=5.07×24+3.6×2.2×2+3.3×1.3×3+98.4×9+2.2×1.8×2+1.28×8.2
=121.68+3.6×2.2×2+3.3×1.3×3+98.4×9+2.2×1.8×2+1.28×8.2
=121.68+7.92×2+3.3×1.3×3+98.4×9+2.2×1.8×2+1.28×8.2
=121.68+15.84+3.3×1.3×3+98.4×9+2.2×1.8×2+1.28×8.2
=121.68+15.84+4.29×3+98.4×9+2.2×1.8×2+1.28×8.2
=121.68+15.84+12.87+98.4×9+2.2×1.8×2+1.28×8.2
=121.68+15.84+12.87+885.6+2.2×1.8×2+1.28×8.2
=121.68+15.84+12.87+885.6+3.96×2+1.28×8.2
=121.68+15.84+12.87+885.6+7.92+1.28×8.2
=121.68+15.84+12.87+885.6+7.92+10.496
=137.52+12.87+885.6+7.92+10.496
=150.39+885.6+7.92+10.496
=1035.99+7.92+10.496
=1043.91+10.496
=1054.406
Answer:3.9×1.3×24+3.6×2.2×2+3.3×1.3×3+(3.9×1.3×17+3.6×2.2+3.3×1.3)×9+2.2×1.8×2+1.28×8.2=1054.406
