〖1/1算式〗
    作业：求算式 (1*(100*8%)/(1+6%)+2*1*(100*8%)/(1+6%)^2+3*1*(100*8%)/(1+6%)^3+4*1*(100+100*8%)/(1+6%)^4)/106.93 的值.
    题型：数学计算
    解:
          (1*(100*8%)/(1+6%)+2*1*(100*8%)/(1+6%)^2+3*1*(100*8%)/(1+6%)^3+4*1*(100+100*8%)/(1+6%)^4)/106.93
        =(1*8/(1+6%)+2*1*(100*8%)/(1+6%)^2+3*1*(100*8%)/(1+6%)^3+4*1*(100+100*8%)/(1+6%)^4)/106.93
        =(1*8/1.06+2*1*(100*8%)/(1+6%)^2+3*1*(100*8%)/(1+6%)^3+4*1*(100+100*8%)/(1+6%)^4)/106.93
        =(1*8/1.06+2*1*8/(1+6%)^2+3*1*(100*8%)/(1+6%)^3+4*1*(100+100*8%)/(1+6%)^4)/106.93
        =(1*8/1.06+2*1*8/1.06^2+3*1*(100*8%)/(1+6%)^3+4*1*(100+100*8%)/(1+6%)^4)/106.93
        =(1*8/1.06+2*1*8/1.06^2+3*1*8/(1+6%)^3+4*1*(100+100*8%)/(1+6%)^4)/106.93
        =(1*8/1.06+2*1*8/1.06^2+3*1*8/1.06^3+4*1*(100+100*8%)/(1+6%)^4)/106.93
        =(1*8/1.06+2*1*8/1.06^2+3*1*8/1.06^3+4*1*108/(1+6%)^4)/106.93
        =(1*8/1.06+2*1*8/1.06^2+3*1*8/1.06^3+4*1*108/1.06^4)/106.93
        =384.122439/106.93
        =3.592279
    答案:(1*(100*8%)/(1+6%)+2*1*(100*8%)/(1+6%)^2+3*1*(100*8%)/(1+6%)^3+4*1*(100+100*8%)/(1+6%)^4)/106.93=3.592279
