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
