Given a language L, etc.
Show that the language L is a regular language.

To show that the language L is a regular language - find/design a dfa that recognizes the language L.

Given a regular expression r, etc.

What is the language L, L = L(r)?

L(r) is the set of all strings etc.

Please increase your Brightness.....

L={ab (a+b)^n} where n>=0}

Every string in this language satrts with ab. So minimum number of states we required to construct a DFA are (2+2) 4.
