1. ## Letter in Letterboxes

Hi,

How many ways can 5 letters be posted in 10 letterboxes ?

But i am really confused with this.

Can anybody help me solving this.

Thanks

2. I got it !

letter one can go in any of the 10 boxes, so 10 ways.

And same goes for remaining 4 letters. so 10.10.10.10.10 = 10 ^5.
