Q1. Show that the following pairs of regular expressions define the same language over the alphabet L = {a, b}. (i) (ab)*a and a(ba)*(ii) (a* + b)* and (a + b)*(iii) (a* + b*)* and (a + b)* [9 marks = 3*3]Q2. Develop a regular expression for the following language over the alphabet P = {a, b} such that it accepts all strings in which the letter b is never tripled. This means that no word contains the substring bbb. [5 marks] Q3. Develop a regular expression for the following language over the alphabet P = {a, b} such that it accepts all strings all words in which a is tripled or b is tripled, but not both. This means each word contains the substring aaa or the substring bbb but not both. [ 6 marks]See More
