作业:求算式 0.018×210000×194000*(1.112×10^(-5)*(40.09-25)-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)*(40.09-25)-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009)
=0.018×210000×194000*(1.112×10^(-5)*(40.09-25)-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009)
=0.018×210000×194000*(1.112×10^-5*15.09-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009)
=0.018×210000×194000*(1.112×10^-5*15.09-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009)
=0.018×210000×194000*(1.112×10^-5*15.09-1.153×10^-5*72.498)/(210000×0.018+194000×0.009)
=0.018×210000×194000*(-0.000704)/(210000×0.018+194000×0.009)
=0.018×210000×194000*(-0.000704)/5526
=3780×194000*(-0.000704)/5526
=733320000*(-0.000704)/5526
=(-516257.28)/5526
=(-93.423322) 答案:0.018×210000×194000*(1.112×10^(-5)*(40.09-25)-1.153×10^(-5)*(97.498-25))/(210000×0.018+194000×0.009)=-93.423322你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
