Q1) Given what you've got so far, which of the three terms needs to be made to disappear?How do I simply AB + BC + AC' + BCD using boolean identities?
Using a K-map I know the answer is AC' + BC.
This is what I did so far
AB + BC + AC' + BCD
AB + AC' + BC(1+D)
AB + AC' + BC
I don't know how to simplify using identities beyond this point.
