〖1/1算式〗
    作业：求算式 (100/((1+13)^1))+(110/((1+13)^2))+(120/((1+13)^3))+(130/((1+13)^4))+(140/((1+13)^5)) 的值.
    题型：数学计算
    解:
          (100/((1+13)^1))+(110/((1+13)^2))+(120/((1+13)^3))+(130/((1+13)^4))+(140/((1+13)^5))
        =(100/(14^1))+(110/((1+13)^2))+(120/((1+13)^3))+(130/((1+13)^4))+(140/((1+13)^5))
        =(100/14)+(110/((1+13)^2))+(120/((1+13)^3))+(130/((1+13)^4))+(140/((1+13)^5))
        =7.142857+(110/((1+13)^2))+(120/((1+13)^3))+(130/((1+13)^4))+(140/((1+13)^5))
        =7.142857+(110/(14^2))+(120/((1+13)^3))+(130/((1+13)^4))+(140/((1+13)^5))
        =7.142857+(110/196)+(120/((1+13)^3))+(130/((1+13)^4))+(140/((1+13)^5))
        =7.142857+0.561224+(120/((1+13)^3))+(130/((1+13)^4))+(140/((1+13)^5))
        =7.142857+0.561224+(120/(14^3))+(130/((1+13)^4))+(140/((1+13)^5))
        =7.142857+0.561224+(120/2744)+(130/((1+13)^4))+(140/((1+13)^5))
        =7.142857+0.561224+0.043732+(130/((1+13)^4))+(140/((1+13)^5))
        =7.142857+0.561224+0.043732+(130/(14^4))+(140/((1+13)^5))
        =7.142857+0.561224+0.043732+(130/38416)+(140/((1+13)^5))
        =7.142857+0.561224+0.043732+0.003384+(140/((1+13)^5))
        =7.142857+0.561224+0.043732+0.003384+(140/(14^5))
        =7.142857+0.561224+0.043732+0.003384+(140/537824)
        =7.142857+0.561224+0.043732+0.003384+0.00026
        =7.704081+0.043732+0.003384+0.00026
        =7.747813+0.003384+0.00026
        =7.751197+0.00026
        =7.751457
    答案:(100/((1+13)^1))+(110/((1+13)^2))+(120/((1+13)^3))+(130/((1+13)^4))+(140/((1+13)^5))=7.751457
