Hi, I have a couple of questions about Boolean. I have to identity which law is being used. I have to pick which one off a numbered list. I don't know if this list is numbered the same everywhere, so I've posted it HERE.

Below is an example of associative law #12, correct?

$\displaystyle (\overline A\bullet \overline B)(A\overline B)=\overline A\bullet A \bullet \overline B \bullet \overline B$

And I'm not as sure on this one, but I'm going to guess distributive law #15.

$\displaystyle (\overline{A\overline{BC}})(AC)+AB=(\overline A+ \overline{\overline B}\overline{\overline C}}})(AC)+AB$

Thanks in advance.
