Work: Calculate the value of equation 0.0005×(20^3-729)-0.0135*(20^2-81)+0.7215*(20-9) .
Question type: Mathematical calculation
Solution:
0.0005×(20^3-729)-0.0135*(20^2-81)+0.7215*(20-9)
=0.0005×7271-0.0135*(20^2-81)+0.7215*(20-9)
=0.0005×7271-0.0135*319+0.7215*(20-9)
=0.0005×7271-0.0135*319+0.7215*11
=3.6355-0.0135*319+0.7215*11
=3.6355-4.3065+0.7215*11
=3.6355-4.3065+7.9365
=-0.671+7.9365
=7.2655
Answer:0.0005×(20^3-729)-0.0135*(20^2-81)+0.7215*(20-9)=7.2655
