In your text or in your notes you should find 3 main rules for logs.

1. log(AB) = logA + logB
2. log (A/B) = logA - logB
3. log (A^n) = nlogA

use them in this question.
You did not use brackets to establish the correct order of operations here, so I will let you finish it.
You probably meant
ln[3√(x^2y)/(x+3)] but I have no way of knowing.
