Question type: Mathematical calculation
Solution:
1088.66×10+68.52+587.7×2-((187×10+23.1)×0.24+(16.5+33×9)×0.12+(299.46+310.95×9+12.35)×0.24+862.1×0.12)
=1088.66×10+68.52+587.7×2-(1893.1×0.24+(16.5+33×9)×0.12+(299.46+310.95×9+12.35)×0.24+862.1×0.12)
=1088.66×10+68.52+587.7×2-(1893.1×0.24+313.5×0.12+(299.46+310.95×9+12.35)×0.24+862.1×0.12)
=1088.66×10+68.52+587.7×2-(1893.1×0.24+313.5×0.12+3110.36×0.24+862.1×0.12)
=1088.66×10+68.52+587.7×2-1341.9024
=10886.6+68.52+587.7×2-1341.9024
=10886.6+68.52+1175.4-1341.9024
=10955.12+1175.4-1341.9024
=12130.52-1341.9024
=10788.6176 Answer:1088.66×10+68.52+587.7×2-((187×10+23.1)×0.24+(16.5+33×9)×0.12+(299.46+310.95×9+12.35)×0.24+862.1×0.12)=10788.6176[2/2 Formula]
Work: Calculate the value of equation -(3.9+3.3+3.6-0.24×3)×(7.2-0.24)×10+(0.7×33+0.9×27+1.8×9+(0.7×48+0.9×29+1.8×7)×9+1.8×4) .
Question type: Mathematical calculation
Solution:
-(3.9+3.3+3.6-0.24×3)×(7.2-0.24)×10+(0.7×33+0.9×27+1.8×9+(0.7×48+0.9×29+1.8×7)×9+1.8×4)
=-10.08×(7.2-0.24)×10+(0.7×33+0.9×27+1.8×9+(0.7×48+0.9×29+1.8×7)×9+1.8×4)
=-10.08×6.96×10+(0.7×33+0.9×27+1.8×9+(0.7×48+0.9×29+1.8×7)×9+1.8×4)
=-10.08×6.96×10+(0.7×33+0.9×27+1.8×9+72.3×9+1.8×4)
=-10.08×6.96×10+721.5
=-70.1568×10+721.5
=(-701.568)+721.5
=19.932 Answer:-(3.9+3.3+3.6-0.24×3)×(7.2-0.24)×10+(0.7×33+0.9×27+1.8×9+(0.7×48+0.9×29+1.8×7)×9+1.8×4)=19.932Your problem has not been solved here? Please go to the Hot Problems section!
