Question

Use the Laws of Logarithms to combine the expression.
ln(a + b) + ln(a − b) − 2 ln c

Answer 1

[(a+b)(a-b)]/c^2
\[a ^{2}-b ^{2}\over c ^{2}\]
I am not sure that this is what they are requesting here??

Answer 2

That's what I got also, but it says I am wrong. Thank you.

Answer 3

Maybe the results should be expressed as: ln((a^2-b^2)/c^2)

Answer 4

ok thank you!
