[br]3 \ln 2 + \frac{1}{3} \ln 4[br]

[br]\rightarrow 3 \ln 2 + \frac{1}{3} \ln 2^2[br]

[br]\rightarrow 3 \ln 2 + \frac{2}{3} \ln 2[br]

[br]\Rightarrow \frac{11}{3} \ln 2[br]

No worries! It's little things that make the difference I think - so many people get tripped up by things they definitely could do on another day -,-
