Work: Calculate the value of equation (20+18.0×0.7+19.4×3.4+19.2×0.8+19.8×1.4)×0.61-2×54×0.87 .
Question type: Mathematical calculation
Solution:
(20+18.0×0.7+19.4×3.4+19.2×0.8+19.8×1.4)×0.61-2×54×0.87
=141.64×0.61-2×54×0.87
=86.4004-2×54×0.87
=86.4004-108×0.87
=86.4004-93.96
=-7.5596
Answer:(20+18.0×0.7+19.4×3.4+19.2×0.8+19.8×1.4)×0.61-2×54×0.87=-7.5596
