How many ways can 10 letters be posted in 5 post boxes, if each of the post boxes can take more than 10 letters?
Solution:Option(A) is correct
Each of the 10 letters can be posted in any of the 5 boxes.
So, the first letter has 5 options, so does the second letter and so on and so forth for all of the 10 letters.
i.e.$ 5×5×5×….×5$ (up-to 10 times)
