    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/(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+3.4/0.000572+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+3.4/0.000572+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+3.4/0.000572+0.8/0+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+3.4/0.000572+0.8/0+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+3.4/0.000572+0.8/0+4.1/0+1/(5×10^(-8))+1.6/(1×10^(-4))+5.3/(1×10^(-4)))
        =16.9/(0.7/0.03456+3.4/0.000572+0.8/0+4.1/0+1/(5×10^(-8))+1.6/(1×10^(-4))+5.3/(1×10^(-4)))
        =16.9/(0.7/0.03456+3.4/0.000572+0.8/0+4.1/0+1/0+1.6/(1×10^(-4))+5.3/(1×10^(-4)))
        =16.9/(0.7/0.03456+3.4/0.000572+0.8/0+4.1/0+1/0+1.6/(1×10^(-4))+5.3/(1×10^(-4)))
        =16.9/(0.7/0.03456+3.4/0.000572+0.8/0+4.1/0+1/0+1.6/0.0001+5.3/(1×10^(-4)))
        =16.9/(0.7/0.03456+3.4/0.000572+0.8/0+4.1/0+1/0+1.6/0.0001+5.3/(1×10^(-4)))
        =16.9/(0.7/0.03456+3.4/0.000572+0.8/0+4.1/0+1/0+1.6/0.0001+5.3/0.0001)
        =16.9/inf
        =inf
    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)))=inf
