[1/1 Formula]
    Work: Calculate the value of equation (20+18.5×1.525+19.8×3.8)×0.66-2×55×√0.66 .
    Question type: Mathematical calculation
    Solution:
          (20+18.5×1.525+19.8×3.8)×0.66-2×55×√0.66
        =123.4525×0.66-2×55×√0.66
        =123.4525×0.66-2×55×0.812404
        =81.47865-2×55×0.812404
        =81.47865-110×0.812404
        =81.47865-89.36444
        =-7.88579

    Answer:(20+18.5×1.525+19.8×3.8)×0.66-2×55×√0.66=-7.88579
