〖1/1算式〗
    作业：求算式 (0.436^2*ln(0.8*11.48/47.97/0.436))/(1-0.436)^2/ln(0.2*11.48/4.074/(1-0.436)) 的值.
    题型：数学计算
    解:
          (0.436^2*ln(0.8*11.48/47.97/0.436))/(1-0.436)^2/ln(0.2*11.48/4.074/(1-0.436))
        =(0.436^2*ln0.439112)/(1-0.436)^2/ln(0.2*11.48/4.074/(1-0.436))
        =-0.156449/(1-0.436)^2/ln(0.2*11.48/4.074/(1-0.436))
        =-0.156449/0.564^2/ln(0.2*11.48/4.074/(1-0.436))
        =-0.156449/0.564^2/ln(0.2*11.48/4.074/0.564)
        =-0.156449/0.564^2/ln0.999245
        =-0.156449/0.564^2/-0.000755
        =-0.156449/0.318096/(-0.000755)
        =-0.49183/(-0.000755)
        =651.430464
    答案:(0.436^2*ln(0.8*11.48/47.97/0.436))/(1-0.436)^2/ln(0.2*11.48/4.074/(1-0.436))=651.430464
