It's really not that hard. Here, I'll show you an example.
\(\sqrt{100}\)
So you take the square root of 100 and see what two number can multiply to get 100.
You can multiply 10 and 10 to get 100.
\(\sqrt{100}\)
^
10 10
Then you see what two numbers you can multiply to get 10. 2 and 5
\(\sqrt{100}\)
^
10 10
^ ^
2 5 2 5
Then you write out the number that you got from least to greastest.
2,2,5,5
Then since you have two 2's and two 5's you combine them to make them one 2 and one 5
You then take both of the numbers outside of the square root.
\(2*5\sqrt{}\)
You then multiply then numbers and get your answer, which is 10.
