Question

Pessoal me ajudem...
preciso do calculo para saber o log 32 e log 25,valendo 20 pontos...

Answer 1

$log\ 32 = log\ 2^5 = 5\ log\ 2\\\\ log\ 2 = 0,3\\\\ log\ 32 = 5(0,30)\\\\ \boxed{log\ 32 = 1,5}$

$log\ 25 = log\ 5^2 = 2\ log\ 5\\\\ log\ 5 = log\ 10-log\ 2\\\\ log\ 5 = 1-0,3010\\\\ \boxed{log\ 5 = 0,69}\\\\ log\ 25 = 2(0,69)\\\\ \boxed{log\ 25 = 1,39}$
