Question

2 log x - log 3 = 1 porfavor ayudadme

Answer 1

Respuesta:

$x=\sqrt{30}=5.477$

 

Explicación paso a paso:

$2log(x)-log(3)=1\\\\log(x^2)-log(3)=1\\\\log\left(\dfrac{x^2}{3}\right)=1\\\\10^{log\left(\dfrac{x^2}{3}\right)}=10^1\\\\\dfrac{x^2}{3}=10\\\\x^2=10\times3\\\\x^2=30\\\\x=\pm\sqrt{30}\\\\\boxed{x=\sqrt{30}=5.477}$
