I find that it's always helpful (also, it's the proper way to express an integral) to include the differential when writing an integral. In this case the differential is dx .

Your result is correct up to the last step.

What is $\displaystyle\ \int{\ln(2)}\,dx\ ?\ \$ Remember, ln(2) is just a constant

It's 4ln(2) which is approximately 2.77 .
