Question

sabendo que log 2=0,3 e log 3=0,48 calcule log 3000​

Answer 1

$log\,3000~=\\\\\\=~log\,(3~.~1000)\\\\\\=~log\,(3~.~10^3)\\\\\\Utilizando~a~propriedade~do~logaritmo~do~produto\\\\\\=~log\,3~+~log\,10^3\\\\\\Utilizando~a~propriedade~do~logaritmo~do~expoente\\\\\\=~log\,3~+~3\,.\,log\,10\\\\\\=~0,48~+~3~.~1\\\\\\=~0,48~+~3\\\\\\=~\boxed{3,48}$
