Question

2log3 x = log3 2 + log3 x​

Answer 1

Oie, Td Bom?!

$2 log_{3}(x) = log_{3}(2) + log_{3}(x)$

$2 log_{3}(x) - log_{3}(x) = log_{3}(2)$

$2 log_{3}(x) - 1 log_{3}(x) = log_{3}(2)$

$(2 - 1) \: . \: log_{3}(x) = log_{3}(2)$

$1 log_{3}(x) = log_{3}(2)$

$log_{3}(x) = log_{3}(2)$

• Bases iguais, iguale os argumentos.

$x = 2$
