I need help on this math problem for my online homework.

"Split the following up into logs of single variables combined with ,,. The problems have all been partially done below. Some spaces should perhaps be left blank. The rest should be filled in with whatever is necessary. Write I in all spaces if that problem is impossible."

I know that the first box is correct, but I'm having trouble with the second box. I thought I had the right answer, but it isn't accepting it. Thank you in advance.
