Answer:

$2 \log_8 8$

Step-by-step explanation:

$3 \log_8 8 - 2 \log_8 4 + \log_8 2 =$

$= 3 \log_8 8 - 2 \log_8 4 + \log_8 2$

$= 3 \log_8 8 - 2 \log_8 8^\frac{2}{3} + \log_8 8^\frac{1}{3}$

$= 3 \log_8 8 - 2 \times \dfrac{2}{3} \log_8 8 + \dfrac{1}{3} \log_8 8$

$= 3 \log_8 8 - \dfrac{4}{3} \log_8 8 + \dfrac{1}{3} \log_8 8$

$= 2 \log_8 8$

Which equals simply 2 since log base 8 of 8 is 1.
