Question: 7. Is the intersection of two regular languages always regular? If not give an example of two languages for which the interse isn't regular. Otherwise

7. Is the intersection of two regular languages always regular? If not give an example of two languages for which the interse isn't regular. Otherwise describe an approach to proving that the intersection must always be 8. Show the language L of "triple words" over (a,b) isn't regular. By triple word we mean a string the form www where wE fa,b)'. Use the pumping lemma for regular languages. Be sure to say what triple word you are attempting to pump and why the pumped string cannot be a triple word
