Question

Here are two relations:
R(A,B): {(0, 1), (2,3), (0, 1), (2,4), (3,4)}
S(B, C): {(0, 1), (2, 4), (2, 5), (3, 4), (0, 2), (3, 4)}
Compute the following: a) 11'A+B.A2,B2(R); b) 71'B+l,C-l(S); c) TB,A(R); d) TB,c(S); e) J(R); f) J(S); g) /A, SUM(Bj(R); h) IB.AVG(C)(S'); ! i) !A(R); ! j) IA,MAX(C)(R t:><1 S); k) R ~L S; I) R ~H S; m) R ~ S; n) R ~R.B<S.B S.

I want to know the solution for j to m
