Question

How do u know when to use the product or quotient property when working with logs?

Answer 1

if it's multiplication it's the sum of logs
if it's division, it's the difference of logs

or
ln(ab) = ln(a) + ln(b)
ln(a/b) = ln(a) - ln(b)

Answer 2

log(a) - log(b) = log(a/b)

log(a) + log(b) = log(a*b)

They're just properties of logarithms.

Answer 3

Thanks all..... the second one makes mere sense to me :)
