Answer
There is deep relationship between logical equivalencies and set identities .Set identities can be derived from logical equivalencies and vice versa. Both are used in logic and set theory .Both are special case of identities that hold for Boolean algebra.
Work Step by Step
As we know that if want to solve particular problem using set identities, logical equivalences give us same answer. Moreover by getting knowledge that a typical set identity refers to some logical equivalence identity we can smooth our work.
