The missing value in the logarithm are as follows:

  • log₃ 7 - log₃ 2 = log₃ (7 / 2)
  • log₉ 7 + log₉ 4 =  log₉ 28
  • log₆ 1 / 81  =  
  • - 4 log₆ 3

How to solve logarithm?

Using logarithm rule,

logₐ b - logₐ c = logₐ (b / c)

logₐ b + logₐ c = logₐ (b × c)

Therefore,

log₃ 7 - log₃ 2 = log₃ (7 / 2)

log₉ 7 + log₉ 4 = log₉ (7 × 4) =  log₉ 28

log₆ 1 / 81 = log₆ 81⁻¹ = log₆ 3⁻⁴ =  - 4 log₆ 3
