Work: Calculate the value of equation 64.9×3.8-1/2×20×0.76×3.82-1/6×19.4×0.76×3.83 .
Question type: Mathematical calculation
Solution:
64.9×3.8-1/2×20×0.76×3.82-1/6×19.4×0.76×3.83
=246.62-1/2×20×0.76×3.82-1/6×19.4×0.76×3.83
=246.62-0.5×20×0.76×3.82-1/6×19.4×0.76×3.83
=246.62-10×0.76×3.82-1/6×19.4×0.76×3.83
=246.62-7.6×3.82-1/6×19.4×0.76×3.83
=246.62-29.032-1/6×19.4×0.76×3.83
=246.62-29.032-0.166667×19.4×0.76×3.83
=246.62-29.032-3.23334×0.76×3.83
=246.62-29.032-2.457338×3.83
=246.62-29.032-9.411605
=217.588-9.411605
=208.176395
Answer:64.9×3.8-1/2×20×0.76×3.82-1/6×19.4×0.76×3.83=208.176395
