Work: Calculate the value of equation (20+17×2.1+18.5×3+18.6×2.5+19.1×6.2+19.5×(4.81-4.3))×0.4217-2×12×0.6494 .
Question type: Mathematical calculation
Solution:
(20+17×2.1+18.5×3+18.6×2.5+19.1×6.2+19.5×(4.81-4.3))×0.4217-2×12×0.6494
=(20+17×2.1+18.5×3+18.6×2.5+19.1×6.2+19.5×0.51)×0.4217-2×12×0.6494
=286.065×0.4217-2×12×0.6494
=120.633611-2×12×0.6494
=120.633611-24×0.6494
=120.633611-15.5856
=105.048011
Answer:(20+17×2.1+18.5×3+18.6×2.5+19.1×6.2+19.5×(4.81-4.3))×0.4217-2×12×0.6494=105.048011
