To evaluate an integral is to find out the exact value of it. Therefore there should be no unknown within the solution. For (a), recall that integrating 1/x gives you ln(x).

Hope this helps! (:

Oh yes, you can further simplify by converting 4ln4 to 4ln2^2, and then bring the power forward to multiply by 4 to get 8ln2. The value of either is the same (:
