logbq + 8 logbt
= logb
(q2) + logb (t8)
= logb
( q2t8)

4 log x – 6 log (x + 2)
= log x4 – log (x + 2)^6
= log ( x4/ ( x + 2)^6)

258 / 6 = 43
Hope this helps!
To change a mixed fraction, you'd multiply the number upfront, times the denominator, and then add that product to the numerator
that IS the new numerator, and you keep the denominator
