Question

logaritmo nivel facil...urgenteeee

Answer 1

E aí mano,

aplique a definição de logaritmos:

$log_bc=k~\to~b^k=c\\\\ log_50,000064=x\\\\ veja~que~0,000064= \dfrac{64}{1000.000}= \dfrac{64\div64}{1000.000\div64}= \dfrac{1}{15.625}:\\\\ log_5 \dfrac{1}{15.625}=x\\\\ 5^x= \dfrac{1}{15.625}\\\\ 5^x= \dfrac{1}{5^6}\\\\ \not5^x=\not5^{-6}\\\\ \large\boxed{\boxed{x=-6}}$

Tenha ótimos estudos =))
