    作业：求算式 16.9/(0.7/0.03456+3.4/(5.72×10-4)+0.8/(4.6×10-4)+4.1/(1.74×10-4)+1/(1.73×10-4)+1.6/(0.003×10-4)+5.3/(0.004×10-4)) 的值.
    题型：数学计算
    解:
          16.9/(0.7/0.03456+3.4/(5.72×10-4)+0.8/(4.6×10-4)+4.1/(1.74×10-4)+1/(1.73×10-4)+1.6/(0.003×10-4)+5.3/(0.004×10-4))
        =16.9/(0.7/0.03456+3.4/53.2+0.8/(4.6×10-4)+4.1/(1.74×10-4)+1/(1.73×10-4)+1.6/(0.003×10-4)+5.3/(0.004×10-4))
        =16.9/(0.7/0.03456+3.4/53.2+0.8/42+4.1/(1.74×10-4)+1/(1.73×10-4)+1.6/(0.003×10-4)+5.3/(0.004×10-4))
        =16.9/(0.7/0.03456+3.4/53.2+0.8/42+4.1/13.4+1/(1.73×10-4)+1.6/(0.003×10-4)+5.3/(0.004×10-4))
        =16.9/(0.7/0.03456+3.4/53.2+0.8/42+4.1/13.4+1/13.3+1.6/(0.003×10-4)+5.3/(0.004×10-4))
        =16.9/(0.7/0.03456+3.4/53.2+0.8/42+4.1/13.4+1/13.3+1.6/(-3.97)+5.3/(0.004×10-4))
        =16.9/(0.7/0.03456+3.4/53.2+0.8/42+4.1/13.4+1/13.3+1.6/(-3.97)+5.3/(-3.96))
        =16.9/18.977339
        =0.890536
    答案:16.9/(0.7/0.03456+3.4/(5.72×10-4)+0.8/(4.6×10-4)+4.1/(1.74×10-4)+1/(1.73×10-4)+1.6/(0.003×10-4)+5.3/(0.004×10-4))=0.890536
