Find perfect squares and drag them out!

7 - No perfect square
225 = 15^2 so $\sqrt{225} = 15$
600 = 6*100 = 6*10^2 so $\sqrt{600} = 10\sqrt{6}$

Tackle all the constants like that.

Variables are a little different.

$\sqrt{x^{2}} = x$ $\large IF$ you know that $x \ge 0$

If you do not know that, then $\sqrt{x^{2}} = |x|$.  BeVERY careful with this.
