Question

dados log2=0,3010 e log5=0,699, calcule log 5/2

Answer 1

Olá,

só usar a p2, propriedade do quociente..

$\log\left( \dfrac{a}{b}\right)\Rightarrow \log(a)-\log(b)$

--------------------

$\log\left( \dfrac{5}{2}\right)=\log(5)-\log(2)\\\\ \log\left( \dfrac{5}{2}\right)=0,699-0,301\\\\ \Large\boxed{\log\left( \dfrac{5}{2}\right)=0,398}$
