    Digital Logic...PLEASE HELP!

    Can someone please simplfy A(C+AB')!??

    Im having trouble with it because when you expand to AC + AAB', what happens with the double A? Does that just make it A?

    Please help!

    Not knowing the particular textbook notation, I will guess that AA=A by idempotency. That is normal in Boolean Algebras.
