Thank you for all of your help! I figured it out :)

how in (2) when you went from (k+1)!=(k+1)(k!)>(k+1)k^2 to (k+1)(k+2)>(k+1)^2

on (2) when you went from (k+1)!= (k+1)(k!)> (k+1)2^k to (k+1)(k^2)> (k+1)^2 why did you get rid of the k!

do you see what i mean? that what you solved was n!>2^n where I need to solve n!>n^2?

I need to prove n!>n^2 not 2^n i have done this proof before

yes i do know how to do them, this one is just stumping me, to how to prove it, i know my basis step is when n=4 and then we assume P(n) is true and prove that P(n+1) is also true. I multiplied both sides of my inequality by (n+1) to get n!(n+1)>n^2(n+1) which is equal to (n+1)!>n^2(n+1) then i...

yes it is true when n>3, how do you prove it when n>3

I have to do an induction proof that n!>n^2
