Math gurus, please help
So I know there are some math wizards here. I'm stuck on a logarithm problem. Any one here good at math? You're help is appreciated. If you can include the steps getting you there instead of just the answer it would help me learn how to solve another one of these problems I have. Thanks in advance if anyone can answer this.
Express 2/3[ln(x^2-9) - ln(x+3)] + ln(x+4) as a single logarithm. This is as far as I've got. I know at some point I have to use the quotient rule but at this point I'm just stuck if I'm even right at this point. = 2/3ln(x^2-9) - 2/3ln(x+3) + ln(x+4) = ln[(x^2-9)^(2/3)] - ln(x+3)^(2/3) + ln(x+4)

I might be a bit rusty..
ln|(((x^2-9)/(x+3))^(2/3))*(x+4)|

Thank you CMT, with your help I see exactly where I went wrong. I really have to bow down to people who know this stuff like it's nothing.
