Question

propriedade dos logaritimos 1) dados log²=03010=04771, caucule log 12:

Answer 1

Propriedade dos logs

$log\ a*b = log\ a+log\ b\\\\ log\ a^2 = 2\ log\ a$

$log\ 12 = log\ 2^2*3\\\\ log\ 12=2\ log\ 2+log\ 3\\\\ log\ 12 = 2(0,301)+0,477\\\\ log\ 12 = 0,602+0,477\\\\ \boxed{log\ 12 = 1,079}$
