Question 416590: I am struggling with square roots. What is the SR of (R+3) squared?

The square root of anything squared is just that same thing back; however, this result is ALWAYS positive (or zero if it was originally zero). Basically, think of the square root "undoing" the square.


So this means that for any real x. Take note of the absolute value bars.


So in your case, x=R+3, which means that


Now if you make the claim that R is a nonnegative number, then you can say because you won't have to worry about negative numbers.
