Two radioactive nuclides `A` and `B` have decay constant `10lambda` and `lambda` respectively. If initially they have same number of nuclei, calculate the ratio of nuclei of `A` and `B` after a time `1//9lambda`

Two radioactive materials A and B have decay constants 10lambda and lambda , respectively. If initially they have the same number of nuclei, then the ratio of the number of nuclei of A of that of B will be 1//e after a time :

Two radioactive material A and B have decay constants 10 lambda and lambda , respectively. If initially they have a the same number of nuclei, then the ratio of the number of nuclei of A to that of B will be 1//e after a time 1/(n lambda) , where n is ___________
