Prove that If L1 is linear and L2 is regular, L1×L2 is a linear Language.
Hopefully this will clear all your doubts.If you still face any query let me know in the comment section.Thank You.
Below is a snapshot of the answer.
Prove that If L1 is linear and L2 is regular, L1×L2 is a linear Language.
For Language L1 and L2 prove or disprove (L1 union L2)*=L1* intersection L2*
Define nor operation for the language as follows. nor(L1, L2) = {w : w E L1 or w E L2} Show that the family of regular languages is closed under the nor operation. Define nor operation for the language as follows. nor(L1, L2) = {w : w E L1 or w E L2} Show that the family of regular languages is closed under the nor operation.
Question 4. Let L1 be the language denoted by ab∗ a ∗ and let L2 be the language denoted by a ∗ b ∗ a Write a regular expression that denotes the language L1 ∩ L2.
If L1 and L2 are Regular Languages, then L1 ∪ L2 is a CFL. Group of answer choices True False Flag this Question Question 61 pts If L1 and L2 are CFLs, then L1 ∩ L2 and L1 ∪ L2 are CFLs. Group of answer choices True False Flag this Question Question 71 pts The regular expression ((ac*)a*)* = ((aa*)c*)*. Group of answer choices True False Flag this Question Question 81 pts Some context free languages are regular. Group of answer choices True...
-. If L and L2 are regular languages, show the the language BothOr Neither is also regular. Both Or Neither is the language that contains strings that are in both L1 and L, or in neither L or L2.
2. If L1 and L2 are regular languages, which of the following are regular languages? Provide justification for your answers. a. L1 U L2 b. L1L2 c. L1 n L2
a) if L1 is recognisable but not decidable, L2 is decidable but not recognisable, then prove L1 U L2 is undecidable? b) if L1 is recognisable but not decidable, L2 is recognisable but not decidable, then prove L1 U L2 is undecidable?
2. If L is a regular language, prove that the language 11 = { uv/ u E 1 , |v|-2) is also regular. (Hint: Can you build an NFA of L1 using an NFA of a language L? Use N, the NFA of the language L)
Given sigma={a, b} And languages L1, L2 contain in sigma^* I need to prove/disprove the following claim:
Question 3. Write down a regular expression that denotes the following language. L = {a mb n : m + n is even} Question 4. Let L1 be the language denoted by ab∗ a ∗ and let L2 be the language denoted by a ∗ b ∗ a Write a regular expression that denotes the language L1 ∩ L2.
