=E. Exercise 2: (20 points) For each question TRUE or False 1) 0 = {x}. 2) 0 3) kau b)* (a U =) b*= (a u b)* ab* 4) (a u b)*a* u b=(a u b)*a* u(a u b)*a* U b) 5) ((a u b)*)*= (a u b)* 6) ((a u b)+)* = (a u b)* 7) a ((a u b)(b u a))* u a((a U b) a )* ua ((b U a) b )* = a ((a u b)(b u a) 8) (a u b)* b (a v b)* u(a u b)* a (a u b)* = (a u b)* 9) (a u b)* b (a u b)* u(a u b)* a (a u b)* = (a u b)+ 10) (a u b)* b a (a u b)* u a*b* = (a u b)* 11) a* b (a u b)* = (a u b)* b (a v b)* 12) Ifa and are any two regular expressions, then (au B)* = a(Baua) 13) If a and are any two regular expressions, then (ap)*a = a(Ba)* 14)(ab)*a = a(ba)* 15)(a u b)* b (a u b)* = a* b (a u b)*
