It is A Bc if they have the same base (here, they have the same base as 3) THEN AND ONLY THEN can you add the exponents together

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
