[1/1 Formula]
    Work: Calculate the value of equation 1.3×((0.3+0.2+0.16+3)×0.9×0.9+(24+1.5)×1.8×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9+0.28) .
    Question type: Mathematical calculation
    Solution:
          1.3×((0.3+0.2+0.16+3)×0.9×0.9+(24+1.5)×1.8×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9+0.28)
        =1.3×(3.66×0.9×0.9+(24+1.5)×1.8×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9+0.28)
        =1.3×(3.66×0.9×0.9+25.5×1.8×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9+0.28)
        =1.3×40.1436+1.5×((2.5+2.0)×0.9×0.9+0.28)
        =1.3×40.1436+1.5×(4.5×0.9×0.9+0.28)
        =1.3×40.1436+1.5×3.925
        =52.18668+1.5×3.925
        =52.18668+5.8875
        =58.07418

    Answer:1.3×((0.3+0.2+0.16+3)×0.9×0.9+(24+1.5)×1.8×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9+0.28)=58.07418
