〖1/1算式〗
    作业：求算式 ((3.77%/1)+(3.77%/1.03)+(3.77%/(1.03)^2)+(3.77%/(1.03)^3)+(3.77%/(1.03)^4)+(1/(1.03)^4))/(1.03)^(9/12) 的值.
    题型：数学计算
    解:
          ((3.77%/1)+(3.77%/1.03)+(3.77%/(1.03)^2)+(3.77%/(1.03)^3)+(3.77%/(1.03)^4)+(1/(1.03)^4))/(1.03)^(9/12)
        =(0.0377+(3.77%/1.03)+(3.77%/(1.03)^2)+(3.77%/(1.03)^3)+(3.77%/(1.03)^4)+(1/(1.03)^4))/(1.03)^(9/12)
        =(0.0377+0.036602+(3.77%/(1.03)^2)+(3.77%/(1.03)^3)+(3.77%/(1.03)^4)+(1/(1.03)^4))/(1.03)^(9/12)
        =(0.0377+0.036602+(3.77%/1.03^2)+(3.77%/(1.03)^3)+(3.77%/(1.03)^4)+(1/(1.03)^4))/(1.03)^(9/12)
        =(0.0377+0.036602+0.035536+(3.77%/(1.03)^3)+(3.77%/(1.03)^4)+(1/(1.03)^4))/(1.03)^(9/12)
        =(0.0377+0.036602+0.035536+(3.77%/1.03^3)+(3.77%/(1.03)^4)+(1/(1.03)^4))/(1.03)^(9/12)
        =(0.0377+0.036602+0.035536+0.034501+(3.77%/(1.03)^4)+(1/(1.03)^4))/(1.03)^(9/12)
        =(0.0377+0.036602+0.035536+0.034501+(3.77%/1.03^4)+(1/(1.03)^4))/(1.03)^(9/12)
        =(0.0377+0.036602+0.035536+0.034501+0.033496+(1/(1.03)^4))/(1.03)^(9/12)
        =(0.0377+0.036602+0.035536+0.034501+0.033496+(1/1.03^4))/(1.03)^(9/12)
        =(0.0377+0.036602+0.035536+0.034501+0.033496+0.888487)/(1.03)^(9/12)
        =1.066322/(1.03)^(9/12)
        =1.066322/1.03^(9/12)
        =1.066322/1.03^0.75
        =1.066322/1.022416662229494
        =1.042943
    答案:((3.77%/1)+(3.77%/1.03)+(3.77%/(1.03)^2)+(3.77%/(1.03)^3)+(3.77%/(1.03)^4)+(1/(1.03)^4))/(1.03)^(9/12)=1.042943
