Question

DESENVOLVA A EXPRESSÃO 

Answer 1

E aí Lucas,

use as seguintes propriedades de log:

$log(ab)~\to~log(a\cdot b)~\to~loga+logb~~~~~~~.\\\\ log\left( \dfrac{a}{b}\right)~\to~loga-logb\\\\ logb^a~\to~a\cdot logb$

___________________

$log\left( \dfrac{x^3y^4}{z^2w}\right)=logx^3y^4-logz^2w\\\\ log\left( \dfrac{x^3y^4}{z^2w}\right)=logx^3+logy^4-logz^2+logw\\\\\\ \large\boxed{\boxed{log\left( \dfrac{x^3y^4}{z^2w}\right)=3logx+4logy-2logz+logw}}~~~~.\\ .$
