How can i simplify these expressions?

  • 1. log(2A) + log(B) - log(AB) 2. ln(ab^t) - ln((ab)^t) - ln(a) please help walk me through the process of how to simplify these! ty!

  • Answer:

    log(x) + log(y) = log(xy) log(x) - log(y) = log(x/y) log(2A) + log(B) - log(AB) = log(2A·B/(AB)) = log(2) ::::: log(xⁿ) = n·log(x) http://www.flickr.com/photos/dwread/7158031050/
