If R = ((1, 1), (3, 1), (2, 3), (4, 2)), then which of the following represents R2, where R2 is R
composite R?
(a) ((1,1), (3, 1), (2, 3), (4, 2))
(b) ((1, 1), (9, 1), (4, 9), (16, 4))
(c) ((1, 1), (2, 1), (4, 3), (3, 1))
 
how to solve.

R = ((1, 1), (3, 1), (2, 3), (4, 2))

RoR=R2=((1, 1), (3, 1), (2, 3), (4, 2))((1, 1), (3, 1), (2, 3), (4, 2))

             =((1, 1), (3, 1), (2, 1), (4, 3))

take first set (1,1) then take second element of this subset check in the other set R is there any starting with 1 if yes then take its second element and make a subset in R2 similarly check for all.

like (4,2) (2,3)=(4,3)in R2

 so answer will be D

Which of the following statement is/are true about pumping lemma for regular language? (a) If L is regular then Pumping lemma must be satisfied. (b) If the Pumping lemma is not satisfied for the language L (for every possible division of w = xyz; where w ε L) then L is definitely non-regular. (c) If L = a i 2 | i ≥ 0 then pumping lemma is always satisfied for L* . (d) If L = a 2n b 3m | n, m > 0 then pumping length can be 5.
