ohh , so good information :)

Ok, I got it.

"False EPI = EPI of POS form Kmap"

---

• The maxterm is called false minterms.
• the prime implicant obtained by using the maxterm is called a false prime implicant.
• the FPI which contains at least one $0$ which cannot be covered by other FPI is called essential false prime implicant.

Here false PI=3 and essential false prime implicant=2 

Answer 1

in this case epi=pi=2 but if we are make single term ring in two pair  ring then it is wrong because here copletely share by two term ring   if cosider then it is wrong
