comment Checking $f_n(x) = \frac{nx}{n+1}$ for uniform convergence
You have calculated the supremum wrong. It will be $\infty$, not n. Clearly $|x|$ is not bounded in $\mathbb R$, so how could $|x|/(n+1)$ be bounded.

comment $n!>n^m$ for $n\ge?$
Induction on what? I think I should use the fact that $log( n!)> n$, for $n \ge 4$.

I don't think you should use induction on this.

comment Let the function $f:[a,b] \to \mathbb R$ be Lipschitz. Show that $f$ maps a set of measure zero onto a set of measure zero
Ok, I solved it. Thanks @Martin!

How to show that and Lebesgue measurable set can be expressed as union of an $F_\sigma$ and a Null set?
