2) two c's in a row can turn into a b

3) any word can be doubled


now how can i change CAC into CAAC while following those rules


also when you double you have to double all letters

Verified Answer :

CAC can be changed into CAAC. This is because the first rule says that any letter can change into an A so
 CAC=CAA
The last condition says that when you double , you have to double all letters,
Since A has been doubled,C needs to be doubled too.So:
CAA=CAAC
