Is my induction solution correct? Jun15 comment $3^{3n+1} < 2^{5n+6}$ for all non-negative integers $n$. Is my induction solution correct? But is $3^3∗2^{5n+6}=2^{5(k+1)+6}$? How do i show it?

Jun15 revised What do you use for your basis step when its domain is all integers? added 102 characters in body Jun15 comment What do you use for your basis step when its domain is all integers? No i know you can solve it using a direct proof but what if were asked to use induction. I only used it as an example Jun15 asked What do you use for your basis step when its domain is all integers? Jun9 comment Prove that $n! < n^n$ where n >1 and is an integer , why do some people say my solution is wrong? wait ill try to solve it again Jun9 asked Prove that $n! < n^n$ where n >1 and is an integer , why do some people say my solution is wrong? Jun8 comment Why is this summation formula wrong? @Ted check on your calculator Jun8 comment Why is this summation formula wrong? @RonGordon fixed, but still the second summation doesn't match.
