You can put this solution on YOUR website!
Write as the sum/difference of logs:
ln%28xy%2F5z%5E2%29 It's not clear from your post whether it's %285z%29%5E2 or 5%2Az%5E2
I.ll assume %285z%29%5E2
ln%28xy%2F%285z%29%5E2%29+=+ln%28xy%29-ln%28%285z%29%5E2%29=ln%28x%29%2Bln%28y%29-2%2Aln%285z%29+=+ln%28x%29%2Bln%28y%29-2%2Aln%285%29%2B2%2Aln%28z%29
