[1/1 Formula]
    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
