Answer:

Step-by-step explanation:
Key facts are:
- log ab = log a + log b
- log a/b = log a - log b
- log aᵇ = b log a
So...
2 log 5/8 + log 128/125 + log 5/2
= 2 log 5 - 2 log 8 + log 128 - log 125 + log 5 - log 2
= 2 log 5 - 2 log 2³ + log 2⁷ - log 5³ + log 5 - log 2
= 2 log 5 - 6 log 2 + 7 log 2 - 3 log 5 + log 5 - log 2
= (2 - 3 + 1) log 5 + (-6 + 7 - 1) log 2
= 0 + 0
= 0
