Here is the problem:

My work:
log(x^2-4)-log(x^3)-log(x+1)
=2log(x-4)-3log(x)-log(x+1)
Is that correct?

You can put this solution on YOUR website!
your work:
log%28x%5E2-4%29-log%28x%5E3%29-log%28x%2B1%29 this is correct
= 2log%28%28x-4%29%29+-3log%28%28x%29%29-log%28%28x%2B1%29%29 ...this part 2log%28%28x-4%29%29 is incorrect; you have %28x%5E2-4%29=x%5E2-2%5E2=%28x-2%29%28x%2B2%29, only if you have log%28%28x-4%29%5E2%29 you can write it as 2log%28%28x-4%29%29
so,
log%28%28x%5E2-4%29%29%2B3log%28%28x%29%29-log%28%28x%2B1%29%29
