| Abstract: | As for real number x,assume that d(x) is the decimal reprsentation in the decile of x.This paper is mainly to analysize the decimal of intelgers l and k in the form (n~2+ln+k(l,n))~(1/2) =1.It's a complete description of the possible value 1,2,…9 as well as the conesponding n-range,with some basic methods. |
