〖1/1算式〗
    作业：求算式 5/((1+11%)^4)+(5*1.2)/((1+11%)^5)+(5*1.2^2)/((1+11%)^6)+(5*1.2^2)/11%/((1+11%)^6) 的值.
    题型：数学计算
    解:
          5/((1+11%)^4)+(5*1.2)/((1+11%)^5)+(5*1.2^2)/((1+11%)^6)+(5*1.2^2)/11%/((1+11%)^6)
        =5/(1.11^4)+(5*1.2)/((1+11%)^5)+(5*1.2^2)/((1+11%)^6)+(5*1.2^2)/11%/((1+11%)^6)
        =5/1.51807041+(5*1.2)/((1+11%)^5)+(5*1.2^2)/((1+11%)^6)+(5*1.2^2)/11%/((1+11%)^6)
        =5/1.51807041+6/((1+11%)^5)+(5*1.2^2)/((1+11%)^6)+(5*1.2^2)/11%/((1+11%)^6)
        =5/1.51807041+6/(1.11^5)+(5*1.2^2)/((1+11%)^6)+(5*1.2^2)/11%/((1+11%)^6)
        =5/1.51807041+6/1.685058155100001+(5*1.2^2)/((1+11%)^6)+(5*1.2^2)/11%/((1+11%)^6)
        =5/1.51807041+6/1.685058155100001+7.2/((1+11%)^6)+(5*1.2^2)/11%/((1+11%)^6)
        =5/1.51807041+6/1.685058155100001+7.2/(1.11^6)+(5*1.2^2)/11%/((1+11%)^6)

        =3.293655+3.560708+3.849414+7.2/0.11/1.870414552161001
        =3.293655+3.560708+3.849414+65.454545/1.870414552161001
        =3.293655+3.560708+3.849414+34.994673
        =6.854363+3.849414+34.994673
        =10.703777+34.994673
        =45.69845
    答案:5/((1+11%)^4)+(5*1.2)/((1+11%)^5)+(5*1.2^2)/((1+11%)^6)+(5*1.2^2)/11%/((1+11%)^6)=45.69845
