    作业：求算式 0.050245*(0.95-13*0.025)*(0.95-14*0.025)*(0.95-15*0.025)*(0.95-16*0.025)*(0.95-17*0.025)*(0.95-18*0.025) 的值.
    题型：数学计算
    解:
          0.050245*(0.95-13*0.025)*(0.95-14*0.025)*(0.95-15*0.025)*(0.95-16*0.025)*(0.95-17*0.025)*(0.95-18*0.025)
        =0.050245*0.625*(0.95-14*0.025)*(0.95-15*0.025)*(0.95-16*0.025)*(0.95-17*0.025)*(0.95-18*0.025)
        =0.050245*0.625*0.6*(0.95-15*0.025)*(0.95-16*0.025)*(0.95-17*0.025)*(0.95-18*0.025)
        =0.050245*0.625*0.6*0.575*(0.95-16*0.025)*(0.95-17*0.025)*(0.95-18*0.025)
        =0.050245*0.625*0.6*0.575*0.55*(0.95-17*0.025)*(0.95-18*0.025)
        =0.050245*0.625*0.6*0.575*0.55*0.525*(0.95-18*0.025)
        =0.050245*0.625*0.6*0.575*0.55*0.525*0.5
        =0.031403*0.6*0.575*0.55*0.525*0.5
        =0.018842*0.575*0.55*0.525*0.5
        =0.010834*0.55*0.525*0.5
        =0.005959*0.525*0.5
        =0.003128*0.5
        =0.001564
    答案:0.050245*(0.95-13*0.025)*(0.95-14*0.025)*(0.95-15*0.025)*(0.95-16*0.025)*(0.95-17*0.025)*(0.95-18*0.025)=0.001564
