1) Put the square root term on one side of the equation and the rest on the other side.
2) Square both sides of the equation. This will remove some or all of the square root signs.
3) May have to repeat steps 1 & 2 several times.

Well, I think the essential thing here is that (sqrt(x))^2 = x. That's what is used when we solve equations involving square roots.

That you can't have a square root of a negative number (unless you're studying imaginary numbers).
For example, if you had the equation:
root(x+5), and you were trying to find x, you'd know that it can't be anything less than -5, because then the equation would equal root(-something), and this is unsolvable.

by "property," maybe it means that the square root has an inverse function (the "square" function).
If it didn't have this property, you could never get rid of the square root, and you wouldn't be able to solve for the variable inside the square root.
