just remember that
lna - lnb = ln(a/b)
lna + lnb = ln(a*b)
ln a^b = b*lna
ln3 - 3ln9 + ln18
ln3 - 3*2ln3 + ln(9*2)
ln3 - 6ln3 + 2ln3 + ln2
-2ln3 + ln2
ln 1/9 + ln2
ln 2/9
#2 has a typo
I suspect a typo in #3 as well, since
ln4 ln8 = ln(8^ln4) or ln(4^ln8)
Please help I don't understand
Contract the expression this is use properties of logarithm to write each expression as a single logarithm with a coefficient of 1.
In3-3 In 9 +In 18
In3-2 in (9=6)
In 3-2 (In 4 In 8)
Thank you so much
