I've got the equation:
$$\log_{10}(x^2 - 16) - 3\log_{10}(x + 4) + 2\log_{10} x$$
I'm looking to express this as a single logarithm. I came up with
$$\log_{10}(x^2 - 16) - \log_{10}(x + 4)^3 + \log_{10} x^2$$
then
$$\log_{10} \left(\frac{x^2(x^2 - 16)}{(x + 4)^3}\right) $$
Please forgive me if I got the number of parentheses wrong.
This looks like the results of most of the examples, would you think further simplification is required?
