The problem
This is not a complete homework problem. I am at the last step of the solution to a long problem and only interested to know whether these following expressions are equivalent.
My answer:
## a \oplus ab \oplus ac ##
Answer in my book:
## a \oplus b \oplus c ##
The attempt
I have tried rewriting that expression and get
## a \oplus ab \oplus ac = a \oplus a(b \oplus c) ##
I am not advancing any longer from there. I am surely missing some algebraic law for boolean expressions. Could you please help me?
