Applying the rule that the sum of logs is the log of the product (and fixing the typo) we get $log frac{2x^2}{3}$ .

Presumably the student meant to combine terms in

$3 log x + log 4 - log x - log 6$

$= log x^3 + log 4 - log x - log 6$

$= log \frac{ 4x^3}{6x}$

$= log frac{2x^2}{3}$

How do you combine like terms in 3\log x + \log _ { 4} - \log x - \log 63\log x + \log _ { 4} - \log x - \log 6?
