Looking at this integral, it seems pretty intimidating at first, but we can do some algebraic manipulation to make it look like a simple u-substitution problem. First we notice that there is a  term that is common within the two separate functions. If we factor it out then the integral becomes:

Now we can apply the rules of u-substitution:

Therefore:

Plugging this result into a calculator results in:

Because the problem statement requires us to round this to three significant figures, the final result is:

This is one of the answer choices.
