Work: Calculate the value of equation 0.0005×(19^3-729)-0.0135*(19^2-81)+0.7215*(19-9) .
Question type: Mathematical calculation
Solution:
0.0005×(19^3-729)-0.0135*(19^2-81)+0.7215*(19-9)
=0.0005×6130-0.0135*(19^2-81)+0.7215*(19-9)
=0.0005×6130-0.0135*280+0.7215*(19-9)
=0.0005×6130-0.0135*280+0.7215*10
=3.065-0.0135*280+0.7215*10
=3.065-3.78+0.7215*10
=3.065-3.78+7.215
=-0.715+7.215
=6.5
Answer:0.0005×(19^3-729)-0.0135*(19^2-81)+0.7215*(19-9)=6.5
