    作业：求算式 ((42/2.3+6.43)^(2)/4)*0.0128/((45*2.3/(45+2*2.3)+3.95)/2)^(4/3)+2.3+(42/2.3)^(2)/19.6 的值.
    题型：数学计算
    解:
          ((42/2.3+6.43)^(2)/4)*0.0128/((45*2.3/(45+2*2.3)+3.95)/2)^(4/3)+2.3+(42/2.3)^(2)/19.6
        =(24.69087^(2)/4)*0.0128/((45*2.3/(45+2*2.3)+3.95)/2)^(4/3)+2.3+(42/2.3)^(2)/19.6
        =(24.69087^2/4)*0.0128/((45*2.3/(45+2*2.3)+3.95)/2)^(4/3)+2.3+(42/2.3)^(2)/19.6
        =152.409765*0.0128/((45*2.3/(45+2*2.3)+3.95)/2)^(4/3)+2.3+(42/2.3)^(2)/19.6
        =152.409765*0.0128/((45*2.3/49.6+3.95)/2)^(4/3)+2.3+(42/2.3)^(2)/19.6
        =152.409765*0.0128/(6.036694/2)^(4/3)+2.3+(42/2.3)^(2)/19.6
        =152.409765*0.0128/3.018347^(4/3)+2.3+(42/2.3)^(2)/19.6
        =152.409765*0.0128/3.018347^1.333333+2.3+(42/2.3)^(2)/19.6
        =152.409765*0.0128/3.018347^1.333333+2.3+18.26087^(2)/19.6
        =152.409765*0.0128/3.018347^1.333333+2.3+18.26087^2/19.6
        =152.409765*0.0128/4.362064287805683+2.3+18.26087^2/19.6
        =152.409765*0.0128/4.362064287805683+2.3+333.459373156900028/19.6
        =1.950845/4.362064287805683+2.3+333.459373156900028/19.6
        =0.44723+2.3+333.459373156900028/19.6
        =0.44723+2.3+17.013233
        =2.74723+17.013233
        =19.760463
    答案:((42/2.3+6.43)^(2)/4)*0.0128/((45*2.3/(45+2*2.3)+3.95)/2)^(4/3)+2.3+(42/2.3)^(2)/19.6=19.760463
