Considering the given functional dependencies, it is observed that S,T,U,V, are prime attributes. Given, R1∩R2≠ϕ Let’s consider R1(S,T,U) and R2(U,V). Since, every attribute is a prime attribute thus all functional dependencies are satisfying the condition of 3NF, that X→Y, where Y should be a prime attribute or X should be a super key.
