Question

log 1/3 com base 1/9 =x​

Answer 1

Olá!

$log_{ \frac{1}{9} }( \frac{1}{3} ) = \frac{ log( \frac{1}{3} ) }{ log( \frac{1}{9} ) } = \frac{ log( \frac{1}{3} ) }{ log( \frac{1}{3} )^{2} } = \frac{ log( \frac{1}{3} ) }{ 2.log( \frac{1}{3} ) } = \frac{1}{2}$

Espero ter ajudado!

Bons estudos!
