sveticcg [70]

Answer:

$\frac{x}{y}=1.3$

Step-by-step explanation:

<u>Informação recuperada:</u>

(UFRGS) Se 10x = 20y , atribuindo 0,3 para log 2 , então o valor de x/y é

1) Primeiro, passando o 10 para o 2º membro como base do logaritmo:

$10x=20y \Rightarrow x=log_{10}20y$

2) Aplicando a propriedade do produto de logaritmo:

$log(AB)= logA+logB$

$x=log_{10}20y \Rightarrow x=log(2+10)y\Rightarrow x=(0.3+1)y \Rightarrow x=1.3y$

3) Como quero o quociente divido ambos os lados por y

$\frac{x}{y}=\frac{1.3y}{y}\Rightarrow \frac{x}{y}=1.3$
