1. The problem statement, all variables and given/known data Hey I'm a little fuzzy on how the induction-proof really works.. and am therefore a little stuck.. I know some parts.. but I need a kick in the right direction.. you don't have to solve it.. just give me a hint or a kick as I said ^^ that would be nice 2. Relevant equations Which nonnegative integers makes the following statement true.. a induction proof would be the best way of solving it i think.. but how do I get started.. and what would be the base theorem..? n²<=n! 3. The attempt at a solution I can logically see what values that is needed.. but help.. please..
