(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

If L is a language over [tex]\Sigma[/tex] then lim n -> inf of L^{n}= [tex]\Sigma[/tex]* iff ([tex]\Sigma[/tex][tex]\cup[/tex]{[tex]\lambda[/tex]})[tex]\subseteq[/tex] L

Also L^{k}= {x_{1}x_{2}...x_{k}| x_{1}, x_{2}, ...x_{k}[tex]\in[/tex] L}

2. Relevant equations

3. The attempt at a solution

I started by saying there is an w is an element of sigma then it is also an element of L so I might use induction but I really don't even know if I started right. Thanks.
