I wrote a whole section on this in a non-traditional format!! You should see my "Basic Algebra: One Step at a Time". The easiest way to find this website is by use of the easy-to-remember and easy-to-spell link www.mathinlivingcolor.com. At the bottom of this page is a link that will take you to my FREE Homepage. Look near the top of this page for the link "Basic, Intermediate, and College Algebra: One Step at a Time", click on "Basic Algebra" and look in Chapter 5 for the section "5.01 Square Roots." The lesson is complete with explanations, examples, and exercises with all the answers. You will especially like the "MATH IN LIVING COLOR". There is also a FREE video of me teaching this topic in my younger years before I retired from teaching. The video can be found from my Homepage by looking for the link "Rapalje Videos in Living Color". Choose Basic Algebra, and look for the video called "Radicals (Square Roots)." I think you will find that my explanations are a LOT easier to understand than the traditional textbooks you are probably using.
Happy New Year!! My Email address is rapaljer@seminolestate.edu if you need to contact me!!
