We know that :


\clubsuit
ln(A) - ln(B) = ln((A)/(B))


\clubsuit
aln(x) = ln(x)^a


\clubsuit
ln(A) + ln(B) = ln(AB)

Using above ideas we can solve the Problem :


(3)/(8)ln(x + 3) = ln(x + 3)^(3)/(8)


ln(x - 3) - ln(x + 3)^(3)/(8) = ln[((x - 3))/((x + 3)^(3)/(8))]


4ln[((x - 3))/((x + 3)^(3)/(8))] = ln[((x - 3))/((x + 3)^(3)/(8))]^4 = ln[((x - 3)^4)/((x + 3)^(3)/(2))]


(1)/(3)lnx + ln[((x - 3)^4)/((x + 3)^(3)/(2))] = ln(x)^(1)/(3) + ln[((x - 3)^4)/((x + 3)^(3)/(2))] = ln[\frac{\sqrt[3]{x}(x - 3)^4}{\sqrt{(x + 3)^(3)}}]

Option 3 is the Answer
