logarithm of a single quantity

This problem is on my summer packet for pre cal honors this year.

Write the following expression as a logarithm of a single quantity:

1/2[ln(x+1)+2ln(x-1)-3ln(2x+5)]+3lnx-2

I tried my best to solve it and ended up with this:

ln[(x+1)(x-1)^2(x^3)/(2x+5)^3]^1/2-2

I'm not sure if the two at the end can sit out like that. It would be great if someone can help =]
