Question

How to expand this logarithm?

ln((-5m-3)\sqrt(-4m-7))

I don't know how to get to that answer.
I only know that the answer has an addition symbol because it is multiplied together.

ln(-(-5m-3))+ln(-(-4m-7)^((1)/(2)))

Answer 1

There is a division symbol, division is subtracted. Are you sure you have the problem stated clearly?

`ln( (-5m-3)/( √(-4m-7) ) )\\ \\ ln(-5m-3) - ln( (-4m-7)^(1/2) ) \\ \\ Power Rule \\ \\ ln(-5m-3) - (1)/(2) ln(-4m-7)`
