〖1/1算式〗
    作业：求算式 0.018×210000×194000*(1.112×10^(-5)*(39.53-25)-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009) 的值.
    题型：数学计算
    解:
          0.018×210000×194000*(1.112×10^(-5)*(39.53-25)-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009)
        =0.018×210000×194000*(1.112×10^(-5)*(39.53-25)-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009)
        =0.018×210000×194000*(1.112×10^-5*14.53-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009)
        =0.018×210000×194000*(1.112×10^-5*14.53-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009)
        =0.018×210000×194000*(1.112×10^-5*14.53-1.153×10^-5*72.498)/(210000×0.018+194000×0.009)
        =0.018×210000×194000*(-0.00071)/(210000×0.018+194000×0.009)
        =0.018×210000×194000*(-0.00071)/5526
        =3780×194000*(-0.00071)/5526
        =733320000*(-0.00071)/5526
        =(-520657.2)/5526
        =(-94.219544)
    答案:0.018×210000×194000*(1.112×10^(-5)*(39.53-25)-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009)=-94.219544
