Work: Calculate the value of equation 0.7×2.513×(6.7×14+2×12+7.8×22+6.4×20+0.8×23+6.8×26+6.2×24+1.2×26+1.6×28)+3.14×0.4×0.4×39.59×(25-10) .
Question type: Mathematical calculation
Solution:
0.7×2.513×(6.7×14+2×12+7.8×22+6.4×20+0.8×23+6.8×26+6.2×24+1.2×26+1.6×28)+3.14×0.4×0.4×39.59×(25-10)
=0.7×2.513×837.4+3.14×0.4×0.4×39.59×(25-10)
=0.7×2.513×837.4+3.14×0.4×0.4×39.59×15
=1.7591×837.4+3.14×0.4×0.4×39.59×15
=1473.07034+3.14×0.4×0.4×39.59×15
=1473.07034+1.256×0.4×39.59×15
=1473.07034+0.5024×39.59×15
=1473.07034+19.890016×15
=1473.07034+298.35024
=1771.42058
Answer:0.7×2.513×(6.7×14+2×12+7.8×22+6.4×20+0.8×23+6.8×26+6.2×24+1.2×26+1.6×28)+3.14×0.4×0.4×39.59×(25-10)=1771.42058
