    解:
          1.21×(0.56×0.001×0.001)×(2+0.6×0.58)×157×330×215×1504.75×1504.75÷586.71÷586.71
        =1.21×0.000001×(2+0.6×0.58)×157×330×215×1504.75×1504.75÷586.71÷586.71
        =1.21×0.000001×2.348×157×330×215×1504.75×1504.75÷586.71÷586.71
        =0.000001×2.348×157×330×215×1504.75×1504.75÷586.71÷586.71
        =0.000002×157×330×215×1504.75×1504.75÷586.71÷586.71
        =0.000314×330×215×1504.75×1504.75÷586.71÷586.71
        =0.10362×215×1504.75×1504.75÷586.71÷586.71
        =22.2783×1504.75×1504.75÷586.71÷586.71
        =33523.271925×1504.75÷586.71÷586.71
        =50444143.429144÷586.71÷586.71
        =85977.984744÷586.71
        =146.542559
    答案:1.21×(0.56×0.001×0.001)×(2+0.6×0.58)×157×330×215×1504.75×1504.75÷586.71÷586.71=146.542559
