[1/1 Formula]
    Work: Calculate the value of equation (20+(18-15.45)×17.3)×0.81-2×5×√0.81 .
    Question type: Mathematical calculation
    Solution:
          (20+(18-15.45)×17.3)×0.81-2×5×√0.81
        =(20+2.55×17.3)×0.81-2×5×√0.81
        =64.115×0.81-2×5×√0.81
        =64.115×0.81-2×5×0.9
        =51.93315-2×5×0.9
        =51.93315-10×0.9
        =51.93315-9
        =42.93315

    Answer:(20+(18-15.45)×17.3)×0.81-2×5×√0.81=42.93315
