Show that n! > n^3 if n is large enough by induction? I get stuck.
I should have been more precise. Yes, I understand induction and have solved other problems OK.
First, the smallest n such that is 6.
Second, assuming it is true for n = k > 6 then show that
We know that
At which point I get stuck!
PS: My first attempt at using LaTex and I don't know why a formulae is moved down relative to the rest of the line that it is in.
