Let's solve the logarithmic equation log(3) + log(x - 2) -log(x). (a) First, we combine the logarithms on the LHS to get the equivalent equation log(x+1) X-10908). 1+2 X -X. (b) Next, we use the fact that log is one-to-one to get the equivalent equation (c) Now we find x = 3 Talk to a Tutor Need Help? Read It

To expand the expression en X infr = drid - ln 158 . 3 as en ( =dna-lnb - a entri-[dns + ln(s) as In(ab) = ln atlnb Ten (X) = lno-locs - In (5)) Now To log 3 solve the equation + log (x-2) = log (2) " log a t logb = log (ab) thence . LHS = log (3(x-2) 6 I Box Now log (3(2-2) = log exe) since log į one to one function » [3(x-2) = x < I Box ! 3) 3X-6 = x = 2x=6 7 1x=31 1 . I Box scanned with CamScanner
