Here is this problem I actually don't know how to approach:
which of the following are T/F for all sets A, B, C
a. A U (B x C) = (A U B) x (A U C)
i think this one is false, i worked it out on a small example
b. A x (B intersection C) = (A x B) intersection (A x C)
c. A x (B x C) = (A x B) x C
where the "x" is cartesian product.
Any idea how to approach this systematically or just a helpful explanation is very much appreciated.
