9.27 In the metro train at the initial stop, 100 passengers entered. How many ways are there to distribute the exit of all these passengers at the next 16 stops of the train?
9.27 The first passenger can exit at any of the 16 stops, as can the second, i.e., for two passengers there are $16^{2}$ possibilities. Therefore, for 100 passengers, there are $16^{100}$ ways.

Answer: $16^{100}$ ways.
