Homework Statement
I'm self-studying Boas book (Mathematical methods in the physical sciences) and one of the problems asks me to prove that for n > 3, n! > 2^n
Homework Equations
There isn't really any "equations".
The Attempt at a Solution
My english is bad so I'll try to explain properly.
I wrote down both series and I can see that with n!, for n > 3 you multiply the previous expression by n to get the next term, but for 2^n every term is simply the last one multiplied by 2. Sorry if the words aren't used correctly but you should see where I'm getting at. However, how do I show this mathematically? Any help would be appreciated!
