#2 Help Me ! » Pre-Calculus - Need help condensing logarithm that starts with a - » 2023-03-07 02:56:33

Hi everyone.

I feel I have a good handle on expanding and condensing logarithms, but I saw a problem on a test prep sheet that threw me:

- ln(5) - ln(3) - 16 ln(x)

Almost all of my problems like this up to this point started with a positive. So I would take the positives and put them in the numerator and put anything that started with a negative in the denominator. But these are all negatives. Should I multiply all values by -1 turning them all positive and then condensing them using multiplication instead? Or maybe I should put a 1 in the numerator and everything else in the denominator?

Note - I know to move the 16 to the exponent spot of the x, but I have no idea what I should do about that negative sign that starts everything off?

Please help? If possible, I am looking for a quick explanation and not just the answer (in case I come across more like these).  Thanks!!!
