Hi

Pencil markings in my second hand textbook obscure the question. Please could someone confirm that Problem 7 is the following:

L1 = (b + ab) * (a + ÃŽâ€º)
L2 = (a + b)*aa(a + b)*

I also can't tell if there's supposed to be a line above the last part of L2.

Many thanks
Rachel

Hi Rachel
Problem 7 is as you have posted above - no extras.
