Question

If log 2=a and log 3=b express log 12 in terms of a and b.

PLEASE HELP ME PLEASEEEEEE!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

Answer:

  2a +b

Step-by-step explanation:

The rule for logarithms is ...

  log(xy) = log(x) +log(y)

__

Applying this to the given problem, we have ...

  log(12) = log(2×2×3)

  = log(2) +log(2) +log(3)

  = a + a + b

  = 2a +b
