possibly mistake in question phrasing.

question says "... sets A,B and C ..."???

unless I am mistaken, when C is written as superscript, it should represent the symbol for "complement of set" (equivalent to using single quotation mark).

LHS

= (AUB) ∩ (A∩B)'

= (AUB) ∩ (A'UB')

= (A∩A') U (A∩B') U (B∩A') U (B∩B')

= ∅ U (A∩B') U (B∩A') U ∅

= (A∩B') U (B∩A')

= (A\B) U (B\A)

= RHS
