〖1/1算式〗
    作业：求算式 0.8/((1+2.7709%))^0.98+1.2/(1+2.7709%)^1.98+1.8/(1+2.7709%)^2.98+102/(1+2.7709%)^3.98 的值.
    题型：数学计算
    解:
          0.8/((1+2.7709%))^0.98+1.2/(1+2.7709%)^1.98+1.8/(1+2.7709%)^2.98+102/(1+2.7709%)^3.98
        =0.8/(1.027709)^0.98+1.2/(1+2.7709%)^1.98+1.8/(1+2.7709%)^2.98+102/(1+2.7709%)^3.98
        =0.8/1.027709^0.98+1.2/(1+2.7709%)^1.98+1.8/(1+2.7709%)^2.98+102/(1+2.7709%)^3.98
        =0.8/1.027709^0.98+1.2/1.027709^1.98+1.8/(1+2.7709%)^2.98+102/(1+2.7709%)^3.98
        =0.8/1.027709^0.98+1.2/1.027709^1.98+1.8/1.027709^2.98+102/(1+2.7709%)^3.98
        =0.8/1.027709^0.98+1.2/1.027709^1.98+1.8/1.027709^2.98+102/1.027709^3.98
        =0.8/1.027147365582454+1.2/1.027709^1.98+1.8/1.027709^2.98+102/1.027709^3.98
        =0.8/1.027147365582454+1.2/1.055608591935378+1.8/1.027709^2.98+102/1.027709^3.98
        =0.8/1.027147365582454+1.2/1.055608591935378+1.8/1.084858450409315+102/1.027709^3.98
        =0.8/1.027147365582454+1.2/1.055608591935378+1.8/1.084858450409315+102/1.114918793211707
        =0.778856+1.2/1.055608591935378+1.8/1.084858450409315+102/1.114918793211707
        =0.778856+1.136785+1.8/1.084858450409315+102/1.114918793211707
        =0.778856+1.136785+1.659203+102/1.114918793211707
        =0.778856+1.136785+1.659203+91.486484
        =1.915641+1.659203+91.486484
        =3.574844+91.486484
        =95.061328
    答案:0.8/((1+2.7709%))^0.98+1.2/(1+2.7709%)^1.98+1.8/(1+2.7709%)^2.98+102/(1+2.7709%)^3.98=95.061328
