Work: Calculate the value of equation 0.0005×(18^3-729)-0.0135*(18^2-81)+0.7215*(18-9) .
Question type: Mathematical calculation
Solution:
0.0005×(18^3-729)-0.0135*(18^2-81)+0.7215*(18-9)
=0.0005×5103-0.0135*(18^2-81)+0.7215*(18-9)
=0.0005×5103-0.0135*243+0.7215*(18-9)
=0.0005×5103-0.0135*243+0.7215*9
=2.5515-0.0135*243+0.7215*9
=2.5515-3.2805+0.7215*9
=2.5515-3.2805+6.4935
=-0.729+6.4935
=5.7645
Answer:0.0005×(18^3-729)-0.0135*(18^2-81)+0.7215*(18-9)=5.7645
