    作业：求算式 6.9×10^6*(0.1/81+192.2*(13×10^(-6)×81)/17.676)^0.25*17.676^2/81^5*0.7669*293/273 的值.
    题型：数学计算
    解:
          6.9×10^6*(0.1/81+192.2*(13×10^(-6)×81)/17.676)^0.25*17.676^2/81^5*0.7669*293/273
        =6.9×10^6*(0.1/81+192.2*(13×10^(-6)×81)/17.676)^0.25*17.676^2/81^5*0.7669*293/273
        =6.9×10^6*(0.1/81+192.2*0.001053/17.676)^0.25*17.676^2/81^5*0.7669*293/273
        =6.9×10^6*0.012685^0.25*17.676^2/81^5*0.7669*293/273
        =6.9×1000000*0.012685^0.25*17.676^2/81^5*0.7669*293/273
        =6.9×1000000*0.33560051444377*17.676^2/81^5*0.7669*293/273
        =6.9×1000000*0.33560051444377*312.440975999999921/81^5*0.7669*293/273
        =6.9×1000000*0.33560051444377*312.440975999999921/3486784401*0.7669*293/273
        =6900000*0.33560051444377*312.440975999999921/3486784401*0.7669*293/273
        =2315643.549662*312.440975999999921/3486784401*0.7669*293/273
        =723501930.7245/3486784401*0.7669*293/273
        =0.207498*0.7669*293/273
        =0.15913*293/273
        =46.62509/273
        =0.170788
    答案:6.9×10^6*(0.1/81+192.2*(13×10^(-6)×81)/17.676)^0.25*17.676^2/81^5*0.7669*293/273=0.170788
