[tex] ^{5} log[/tex](3x 5²) + [tex] ^{7} log[/tex](5 x 7²) + [tex] ^{5} log[/tex]5 - [tex] ^{5} log[/tex]3 - [tex] ^{7} log[/tex]5
=[tex] ^{5} log[/tex]3 + [tex] ^{5} log[/tex]5² + [tex] ^{7} log[/tex]5 + [tex] ^{7} log[/tex]7² - [tex] ^{5} log[/tex]5 - [tex] ^{5} log[/tex]3 - [tex] ^{7} log[/tex]5
=([tex] ^{5} log3[/tex] - [tex] ^{5}log [/tex]3) + 2 + ([tex] ^{7} log[/tex]5 - [tex] ^{7} log[/tex]5) + 2 + 1
= 2 + 2 + 1
= 5
