Using logarithm properties, we can combine the 2 logs on the left hand side: lo g 2 x + lo g 2 6 = 3 ⇒ lo g 2 6 x = 3
Now we can raise everything to a power of 2 and cancel out the log: lo g 2 6 x = 3 ⇒ 2 lo g 2 6 x = 2 3 ⇒ 6 x = 8
Now using simple rearranging we get: 6 x = 8 ⇒ x = 3 4

lo g 2 x + lo g 2 6 lo g 2 ( 6 x ) 6 x ⟹ x = 3 = lo g 2 ( 2 3 ) = 8 = 6 8 ≈ 1 . 3 3
