When Logarithms or In add or subtract?? What to do

[From: ] [author: ] [Date: 12-04-16] [Hit: ]
I honestly just cant find a single example of solving it.Same for In, say there is something like In (1 - P) = .2525 what the hell do you do to get the P out of a situation like that? Not looking for answers just some basics please.-With the logarithm laws,......
I need to get this understood as I keep running into it and I need it confirmed:

I already know if its something like log (5 x 2) that it turns to log (5) + log (2) but...

Suppose there is something like log7 (10x + 13y) ALREADY with a + sign.

How the hell do you simplify that??? You don't go ahead and multiply those two amounts right? What do you do to it? I honestly just cant find a single example of solving it.

Same for In, say there is something like "In (1 - P) = .2525" what the hell do you do to get the P out of a situation like that? Not looking for answers just some basics please.

With the logarithm laws, you won't be able simplify log7(10x + 13y).

However, with ln(1 - p) = 0.2525, you can solve it.
You have to use the inverse function of ln(x), which is e^x.
Raise both sides to e.
e^(ln(1-p)) = e^(0.2525)
It's important to remember that ln(e^x) = x = e^(ln(x))
1 - p = 1.287
p = -0.287

I hope this helps!
