〖1/1算式〗
    作业：求算式 (1000/0.4845056207)/(1+0.4845056207)^1+(4000/0.4845056207)/(1+0.4845056207)^3 的值.
    题型：数学计算
    解:
          (1000/0.4845056207)/(1+0.4845056207)^1+(4000/0.4845056207)/(1+0.4845056207)^3
        =2063.959544/(1+0.4845056207)^1+(4000/0.4845056207)/(1+0.4845056207)^3
        =2063.959544/1.484506^1+(4000/0.4845056207)/(1+0.4845056207)^3
        =2063.959544/1.484506^1+8255.838176/(1+0.4845056207)^3
        =2063.959544/1.484506^1+8255.838176/1.484506^3
        =2063.959544/1.484506+8255.838176/1.484506^3
        =2063.959544/1.484506+8255.838176/3.271492068609827
        =1390.334255+8255.838176/3.271492068609827
        =1390.334255+2523.569675
        =3913.90393
    答案:(1000/0.4845056207)/(1+0.4845056207)^1+(4000/0.4845056207)/(1+0.4845056207)^3=3913.90393
