Answer:

<u>Given</u>

  • log₃ 20 = x and log₃ 2 = y

<u>Properties used</u>

  • <em>log ab = log a  + log b</em>
  • <em>log a/b = log a - log b</em>
  • <em>log aᵇ = b log a</em>

a)

  • log₃ 400 = log₃ (20)² = 2 log₃ 20 = 2x

b)

  • log₃ 80 = log₃ (20*4) = log₃ 20 + log₃ 4 = log₃ 20 + 2log₃ 2 = x + 2y

c)

  • log₃ 40 = log₃ (20*2) = log₃ 20 + log₃ 2 = x + y

d)

  • log₃ 10 = log₃ (20/2) = log₃ 20 - log₃ 2 = x - y
