〖1/1算式〗
    作业：求算式 0.009×210000×194000*(1.112×10^(-5)*(39.49-25)-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009) 的值.
    题型：数学计算
    解:
          0.009×210000×194000*(1.112×10^(-5)*(39.49-25)-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009)
        =0.009×210000×194000*(1.112×10^(-5)*(39.49-25)-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009)
        =0.009×210000×194000*(1.112×10^-5*14.49-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009)
        =0.009×210000×194000*(1.112×10^-5*14.49-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009)
        =0.009×210000×194000*(1.112×10^-5*14.49-1.153×10^-5*72.498)/(210000×0.018+194000×0.009)
        =0.009×210000×194000*(-0.000711)/(210000×0.018+194000×0.009)
        =0.009×210000×194000*(-0.000711)/5526
        =1890×194000*(-0.000711)/5526
        =366660000*(-0.000711)/5526
        =(-260695.26)/5526
        =(-47.176124)
    答案:0.009×210000×194000*(1.112×10^(-5)*(39.49-25)-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009)=-47.176124
