I did an integral and the answer on wolfram is $\frac{1}{5} ln{\frac{3}{2}} + ln{2}$ and it's equal to 0.77424 which is == to my answer which is $\frac{3}{5}(ln3 - ln1) + \frac{2}{5}(ln8-ln6)$

Why are these 2 answers the same? CAn someone help me simplify?

I can get to $\frac{3}{5} ln3 + \frac{2}{5} ln(\frac{4}{3})$
