Question 50915: Hi, I have a multiple choice question and i'm stuck between the two answers.
I have ln (x\square root of yz) =
either lnx - 1\2 (ln y - ln z)
or ln x - 1\2 (ln y + ln z).
I have got as far as ln x - square root ln y SOMETHING ln z
I am just not sure whether the SOMETHING should be plus or minus sign.
thanks for your help.

The ln of a product is the SUM of the logs, so use the positive. The negative is still outside the parentheses.

ln x - 1/2 (ln y + ln z).
