Best ResponseYou've already chosen the best response.0That's the closest I've seen so far, but the one of answer choices says: 4log_4 7^2

Best ResponseYou've already chosen the best response.1\[\log_{4}7^{2} = 2(\log_{4}7) = 2(\log_{7}7/\log_{7}4) = 2(1/\log_{7}2^{2})\] \[2(\log_{7}2^{2}) = 2 * 2(\log_{7}2) = 4\log_{7}2\]
