a is a real number since we use just letters to represent real numbers. if a > 0, then its square root is also a real number, so it has two square roots, one positive and one negative. Be careful when you use the radical sign, because it is looking only for the principal square root of a, which is the positive one. if a < 0, then its square root is an imaginary number.
If you are packing items into a box, you can use square roots along with Pythagorean theorem to help determine if a smaller box could work with items packed diagonally.

Square roots.
You don't need square roots for this, and there is no use for them in this context. You simply divide both sides of the equation by 2.You don't need square roots for this, and there is no use for them in this context.

In the simplest case, it is use to find the diagonal length of a unit square.

The rule you can use is that root(a) x root(b) = root(ab), or root(a) / root(b) = root(a/b). This rule works for real numbers, but if you ever have to handle complex numbers, it is no longer valid. In the case of real numbers, it also works with cubic roots, fourth roots, etc.
A positive real number, such as 17, has two square roots. One is the one your calculator gives you, if you use the square root function. The other is the same number, with a minus sign in front. None of these has an imaginary part. There are no additional complex roots that have a non-zero imaginary part.
