Question

2 log 11/13 + log 130/77 - log 55/91 = log 2

Answer 1

$log { \frac{11}{13} }^{2} + log( \frac{130}{77} ) - log( \frac{55}{91} )$
$= log( \frac{11}{13} \times \frac{11}{13} \times \frac{130}{77} ) - log( \frac{55}{91} )$
$= log( \frac{11}{13} \times \frac{10}{7} ) - log( \frac{55}{91} )$
$= log( \frac{11}{13} \times \frac{10}{7} \times \frac{91}{55} )$
$= log(2)$
