How many set are in a cartisian product? Example:
{(a),(b)} = (ab) Answer is 1 {(a),(b),(c)} = (ab),(ac),(bc) answer is 3 {......,(c),(d)} = (ab),(ac),(ad),(bc),(bd) answer is 5
Let a=1, b=2, c=3, d=4.......
So if we have {1,2,......,50} How many set can we get?
very sinple the answer is 1225 sets.
Any questions for the sinple algebratic formula e-mail me at [email protected]
