Question from textbook review

Hi Mr. G. Some of us have a quick question from the textbook review. #7. d) on page 510 reads: Express the following as a single log: 2 log 3 + 4 log 2. So at first glance this seems like we should be able to bring the coefficients up and get log 3 ^ 2 + log 2 ^ 4, which we can then use the Log Product law to turn into (skipping some steps): log144. However, the textbook says the answer is log128. Is this textbook error or are we doing something wrong? No video necessary by the way
