A regular language over an alphabet ∑ is one that cannot be obtained from the basic languages using the operation ans. All of the mentioned
Concatenation
Kleene*
Union
Solution
The statement is incorrect. A regular language over an alphabet ∑ is one that CAN be obtained from the basic languages using the operations of Concatenation, Kleene*, and Union.
Here's a step-by-step explanation:
-
Basic Languages: These are the simplest form of languages that consist of all strings over an alphabet ∑.
-
Concatenation: This operation combines two languages L1 and L2 to form a new language that consists of all possible strings that can be formed by taking a string from L1 and a string from L2 and concatenating them.
-
Kleene*: This operation is applied to a language L and results in a new language that consists of all possible strings that can be formed by concatenating zero or more strings from L.
-
Union: This operation combines two languages L1 and L2 to form a new language that consists of all strings that are in either L1 or L2.
So, a regular language is one that can be obtained by applying these operations to the basic languages.

or each of the following languages over the alphabet Σ = {a, b, c} specified by the regular expressions (a)–(c),provide two strings in Σ∗ that are members and two strings in Σ∗ that are not members of the language (fourstrings each).(a) ab + a(b) ((bc)∗ + b)a(c) (a + ab + abc)∗(b + c)
Assume the alphabet Σ = {0, 1}. Give three different regular expressions (besides the one given) that specify thelanguage described by this regular expression:((11)∗1∗)∗ + (11 + 1)∗ + (0 + ϵ)∗In each case, explain why your regular expression specifies the same language.Note: For the purposes of this exercise only, changing the order of a union does not count as a different regularexpression.
