Question

Escreva na forma de um único logaritmo 3log84-log816

Answer 1

$3log(84)-log(816) \\ log(84^3)-log(816) \\ log(592704) - log(816) \\ log( \frac{592704}{816} ) \\ log( \frac{12348}{17} )$

Answer 2

$3. log_{8}4- log_{8}16= \\ \\ log_{8} 4^{3}- log_{8}16= \\ \\ log_{8}64- log_{8}16 = \\ \\ log_{8} \frac{64}{16}= \\ \\ log_{8}4$
