    作业：求算式 ((42/2.56+6.43)^(2)/4)*0.0128/((45*2.56/(45+2*2.56)+3.95)/2)^(4/3)+2.56+(42/2.56)^(2)/19.6 的值.
    题型：数学计算
    解:
          ((42/2.56+6.43)^(2)/4)*0.0128/((45*2.56/(45+2*2.56)+3.95)/2)^(4/3)+2.56+(42/2.56)^(2)/19.6
        =(22.83625^(2)/4)*0.0128/((45*2.56/(45+2*2.56)+3.95)/2)^(4/3)+2.56+(42/2.56)^(2)/19.6
        =(22.83625^2/4)*0.0128/((45*2.56/(45+2*2.56)+3.95)/2)^(4/3)+2.56+(42/2.56)^(2)/19.6
        =130.373579*0.0128/((45*2.56/(45+2*2.56)+3.95)/2)^(4/3)+2.56+(42/2.56)^(2)/19.6
        =130.373579*0.0128/((45*2.56/50.12+3.95)/2)^(4/3)+2.56+(42/2.56)^(2)/19.6
        =130.373579*0.0128/(6.248484/2)^(4/3)+2.56+(42/2.56)^(2)/19.6
        =130.373579*0.0128/3.124242^(4/3)+2.56+(42/2.56)^(2)/19.6
        =130.373579*0.0128/3.124242^1.333333+2.56+(42/2.56)^(2)/19.6
        =130.373579*0.0128/3.124242^1.333333+2.56+16.40625^(2)/19.6
        =130.373579*0.0128/3.124242^1.333333+2.56+16.40625^2/19.6
        =130.373579*0.0128/4.567298437721893+2.56+16.40625^2/19.6
        =130.373579*0.0128/4.567298437721893+2.56+269.1650390625/19.6
        =1.668782/4.567298437721893+2.56+269.1650390625/19.6
        =0.365376+2.56+269.1650390625/19.6
        =0.365376+2.56+13.73291
        =2.925376+13.73291
        =16.658286
    答案:((42/2.56+6.43)^(2)/4)*0.0128/((45*2.56/(45+2*2.56)+3.95)/2)^(4/3)+2.56+(42/2.56)^(2)/19.6=16.658286
