Question 383299: Any help explaining the rules of the problem below would be greatly appreciated!
Write as a single log whose coefficient is 1:
ln(x^2-16) - ln(x+4)
_____________________________________________
I tried this but I don't think I have it right at all.
->ln (x-4)(x+4) - ln (x+4)
->ln 4^x/ ln 4^x Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Any help explaining the rules of the problem below would be greatly appreciated!
Write as a single log whose coefficient is 1:
ln(x^2-16) - ln(x+4)
----
The Rule is ln(A)-ln(B) = ln(A/B)
Your Problem:
ln[(x^2-16)/(x+4)]
ln[(x-4)(x+4)/(x+4)]
= ln(x-4)
