[1/1 Formula]
Work: Calculate the value of equation (66.5724+(20+17×2.1+18.5×3+18.6×5.1+19.1×(1.9-1.38))×0.6104-2×19×0.7813)/2×(1.9-1.38) .
Question type: Mathematical calculation
Solution:
(66.5724+(20+17×2.1+18.5×3+18.6×5.1+19.1×(1.9-1.38))×0.6104-2×19×0.7813)/2×(1.9-1.38)
=(66.5724+(20+17×2.1+18.5×3+18.6×5.1+19.1×0.52)×0.6104-2×19×0.7813)/2×(1.9-1.38)
=(66.5724+215.992×0.6104-2×19×0.7813)/2×(1.9-1.38)
=168.724517/2×(1.9-1.38)
=168.724517/2×0.52
=84.362258×0.52
=43.868374
Answer:(66.5724+(20+17×2.1+18.5×3+18.6×5.1+19.1×(1.9-1.38))×0.6104-2×19×0.7813)/2×(1.9-1.38)=43.868374
