hasil dari 5 log 75 - 5 log 12 - 5 log 4 + 5 log 16 =....

[tex] ^{5} log(75) - ^{5} log(12) - ^{5} log(4) + ^{5} log(16) \\ = ^{5} log \: (\frac{75}{12}) - ^{5} log \: ( \frac{4}{16} ) \\ = ^{5} log( \frac{25}{4} ) - ^{5} log \: ( \frac{1}{4} ) \\ = ^{5} log \: ( \frac{ \frac{25}{4} }{ \frac{1}{4} } ) \\ = ^{5} log \: ( \frac{25}{4} \times \frac{4}{1} ) \\ = ^{5} log \: 25 \\ = 2[/tex]
