The e book's answer and your answer are the two precise, however the e book's answer is simplified and yours isn't. once you have 2 sq. root 18, one thank you to simplify it is to get the top factorization of 18, that's: 2 * 3 * 3 by way of fact that there's a "pair" of three's (2 3's in the factorization), you will desire to take out a three and multiply it with the extensive form it incredibly is already outdoors of the sq. root image, which for that reason is a 2, which receives you 6, and save that answer outdoors of the sq. root image. Then, you're taking what's left on your top factorization and multiply them at the same time (if there is greater beneficial than one extensive form, yet for that reason, there is in elementary terms one, that's a 2). After looking this out, save that answer interior the sq. root image. this would desire to furnish you with the e book's simplified and suited suited answer, that's 6 root 2. desire this helped!
