Question: Convert the following DFA to a regular expression, using the State elimination technique: Consider the following identities for regular expressions; some are false and some

  1. Convert the following DFA to a regular expression, using the State elimination technique:

  1. Consider the following identities for regular expressions; some are false and some are true. You are asked to decide which and in case it is false to provide the correct counter example:

  1. 1) R(S + T) = RS + RT

2) (R*)* = R*

3) (RS + R)*R = R(SR + R)*

Use the pumping lemma to prove that the language

A = { 02n 13n 0m | n, m 0 } is not context free.
