Hello,
The problem is this:
2[ln(x) - ln(x + 1) - ln(x - 1)]
I know to distribute the 2 first:
2ln(x) - 2ln(x+1) - 2ln(x-1)
Then take the 2 and make it an exponent:
ln(x)^2 - ln(x+1)^2 - ln(x-1)^2
I know at this point since subtraction is being used we will divide each so:
ln[ x^2 / (x+1)^2] - ln(x-1)^2
I am lost right there and not sure what to do next. Any help would be greatly appreciated.
No, you are just multiplying the top by the reciprocal of the bottom to get rid of your big fraction. It's just to simplify it.
You divided your first two logs correctly, then you needed to divide that by the last subtracted log, from your logs rules, right?
So your log will look like this:
Does that make sense to you?
