Question

PLEASE HELP

Answer 1

Answer:

It is B

Step-by-step explanation:

$ln(x) + ln(y) - ln(z)$

from law of logarithms:

${ \bf{ ln(a) + ln(b) = ln(ab) }} \\ and \\ { \bf{ ln(a) - ln(b) = ln( \frac{a}{b} ) }}$

so, in the question:

$ln(x) + ln(y) - ln(z) \\ \\ = \{ ln(xy) - ln(z) \} \\ \\ = ln( \frac{xy}{z} )$
