Adding 'like' square root terms is like stacking boxes of the same size. For example, 2√2 + 4√2 + 7√2 = . 1 . 13
2.13√2
3. 26
4. 26√2

  2.  13√2

Step-by-step explanation:

You can consider the radical as though it were some (non-numeric) symbol.

Using Ф for √2, this becomes ...

  2Ф +4Ф +7Ф = (2+4+7)Ф = 13Ф

Using √2 for Ф, this becomes ...

  = 13√2

In short, do not be intimidated by the radical expression. Treat it as you would any other symbol for purposes of collecting terms. (Of course, you can only combine "like" radicals.)
