Question

use logarithm properties to expand each question:

Answer 1

log(a^2b^3/c^5)

Answer 2

There are two properties of logarithms which will be quite useful here:

\[\log (ab) = \log(a) + \log(b)\]\[\log (c/d) = \log(c) -\log(d)\]

With those, you can rewrite your equation as the sum of 3 logarithms.

Each of those may be further simplified by using
\[\log x^n = n \log x\]
