I decided to go from one to two pages on Squares and Square Roots:

The Original (simple): Squares and Square Roots

The New One (more advanced): Squares and Square Roots in Algebra

Does it cover it well?

Yes.

Good pages!

The one change I'd make is to add a bit more explanation to when you say √2 * √2 = 2.

Why did the vector cross the road?

It wanted to be normal.

√2 * √2 = √(2*2) = √4 = 2

About that.. ^, if you really want to, you can also state that the √a * √b = √ab is not always true.

For instance, - 1 = i^2 = i * i = √-1 * √-1 = √(-1*-1) = √1 = 1

That is untrue, so if you are really bored enough, you can add that and explain why.'
