Simplify the following roots.

I don't really get it..
Every time that you see a pair of the same numbers, you take it out. Notice how I circled what I took out on the second drawing? Two fives were taken out. Because you know √25 = 5. But I left a 5 inside the root because there isn't another pair of 5 to take out. Therefore, you just leave it inside.
Oh okay I see now! Sorry. Thank you so much!
