Question

if(x)=log(1-1/x^2) then the value of f(2) + f(3) + f(4) ??​

Answer 1

$log( \frac{3}{4} ) + log( \frac{8}{9} ) + log( \frac{15}{16} )$

so we can say that

$log(3) - 2 log(2) + 3 log(2) - 2 log(3) + log(5) + log(3) - 4 log(2)$

so we can say that

$- 3 log(2) + log(10) - log(2) \:$

$1 - 4 log(2) = 1 - 4(.3)$

$- 0.2$
