Expanding we have $$(cd+b'c+bd')(b+d)=bcd+bd'+cd+b'cd$$
Express each function as sum of Minterm and Product of Maxterm.
If you have n-variables then you will have $$2^n$$ products. Following n=3 we have 8 minterm. But my book suggest that there are 16 terms.
I need some clarification on this. Help please.
Another question is why don't we simplified the terms using Boolean Algebra like we normally do?
