4sqrt%28x%29%2B3sqrt%28xy%29%2B7sqrt%28xy%29-sqrt%28x%29

Combine only LIKE TERMS--that is, terms that have the same variables, in this case, inside the square roots.

4sqrt%28x%29-sqrt%28x%29%2B3sqrt%28xy%29%2B7sqrt%28xy%29++++
3sqrt%28x%29%2B10sqrt%28xy%29+++

4(rad)x+3(rad)xy+7(rad)xy-(rad)x
----------------
4sqrt(x) + 3sqrt(xy) + 7sqrt(xy)-sqrtx
= 3sqrt(x) + 10sqrt(xy)
