L={VUV | V,U $\epsilon (a,b)^{*}$ }
consider V=$\epsilon$ and U=$(a+b)^{*}$ then it is complete language.
So L=$(a+b)^{*}$.

For any string x∈{a,b}*, we can treat it as x=ϵxϵ, where v=ϵ,x=u. Therefore, any string x∈{a,b}* is in L. Thus, L = (a + b)*

Give a regular expression to represent salaries as they might appear in employment advertising. Consider that salaries might be given on a per hour, week, month or year basis. They may or may not appear with a dollar sign or ... classified ads in a newspaper, or on-line jobs listings to get an idea of what patterns might be useful.
