Please show step by step and don't copy the answer in another Chegg posted. It's not correct so I will report if it likes the same. For examples regular expressions below, if string of length at least 5 give one example. And If string of length not equal 5 give all example. Describe language given by expression. 1. (b(a U b)*a) u (ab U a)+b) 2. (b U a)*bb U a)(b U a) 3. (a) u ((b*a*)*aa) 4. ((b U a)(a U b)b)+ 5. (b(b U a)) U ((a U aba)*( )+a*b*a) U ( a(E U *) *(b U a)) Note: 0 empty set E epsilon at={a,aa,aaa,...} a* = { ,a,aa,aaa...}
