(a) Union of two non-regular languages cannot be regular. Ans: False. this proof you can assume the true fact that the concatenation of two wiggle.
(j) If L1 and L2 are nonregular languages then L1 ? L2 is also not regular. is thus the concatenation of two regular languages. The regular languages ...
particular Goldbach's conjecture gives examples of two non-regular languages whose concatenation is regular. Introduction.
Consider w? = xy2z = an+kbanb. As long as k > 0 the first half of w? contains all a's

4 L is the concatenation of two regular languages; or 4 0 + 1(0 + 1)?00 — the set of all non-negative binary numerals divisible by and with no.

nonempty alphabet So there are many more nonregular languages than there are reg- ular ones. 8.3 Some Important Closure Properties of Regular Languages.
4 L is the concatenation of two regular languages; or 4 0 + 1(0 + 1)?00 — the set of all non-negative binary numerals divisible by and with no.
