How would I go about expanding a log? I must rewrite the given expression as a sum, difference, or product, of logs.

Question

The problem I am struggling with is:

ln(3ab*5c) .

I've reviewed all my notes and am still struggling. Any help would be appreciated!

Answer 1

Generally speaking LN( x1 * x2 * ... * xN ) = LN(x1) + LN(x2) + .... + LN(xN)

so you got ln(3) + ln(A) + ln(b) + ln(5) + ln(c)
