Two radioactive materials A and B have decay constants $\displaystyle 25 \lambda$ and $\displaystyle 16 \lambda$ respectively. If initially they have the same number of nuclei, then the ratio of the number of nuclei of $\displaystyle B$ to that of $\displaystyle A$ will be " $\displaystyle e$ " after a time $\displaystyle \frac{1}{a \lambda}$. The value of $\displaystyle a$ is \_\_\_\_.
