〖1/1算式〗
    作业：求算式 16.9/(0.7/0.03456+3.4/(5.72×10-4)+0.8/(5×10-8)+4.1/(5×10-8)+1/(5×10-8)+1.6/(1×10-4)+5.3/(1×10-4)) 的值.
    题型：数学计算
    解:
          16.9/(0.7/0.03456+3.4/(5.72×10-4)+0.8/(5×10-8)+4.1/(5×10-8)+1/(5×10-8)+1.6/(1×10-4)+5.3/(1×10-4))
        =16.9/(0.7/0.03456+3.4/53.2+0.8/(5×10-8)+4.1/(5×10-8)+1/(5×10-8)+1.6/(1×10-4)+5.3/(1×10-4))
        =16.9/(0.7/0.03456+3.4/53.2+0.8/42+4.1/(5×10-8)+1/(5×10-8)+1.6/(1×10-4)+5.3/(1×10-4))
        =16.9/(0.7/0.03456+3.4/53.2+0.8/42+4.1/42+1/(5×10-8)+1.6/(1×10-4)+5.3/(1×10-4))
        =16.9/(0.7/0.03456+3.4/53.2+0.8/42+4.1/42+1/42+1.6/(1×10-4)+5.3/(1×10-4))
        =16.9/(0.7/0.03456+3.4/53.2+0.8/42+4.1/42+1/42+1.6/6+5.3/(1×10-4))
        =16.9/(0.7/0.03456+3.4/53.2+0.8/42+4.1/42+1/42+1.6/6+5.3/6)
        =16.9/21.609017
        =0.782081
    答案:16.9/(0.7/0.03456+3.4/(5.72×10-4)+0.8/(5×10-8)+4.1/(5×10-8)+1/(5×10-8)+1.6/(1×10-4)+5.3/(1×10-4))=0.782081
