Decide for which natural numbers the inequality3^n > n^3 is true.Prove your claim using mathematical induction Solution base case: n=4 3^(n+1)=3*3^n and (n+1)^3=n^3+3n^2+3n+1. What does 3^n+1/ (n+1)^3 equal? take the limit and use Lhopitals Rule toevaluate: lim, as n approaches infty, 3*3^n/(n^3 +3n^2+3n+1). Nowdivide the top and bottom by n^3. and you get the same limit aswith n. hope that helps.
