2sqrt2

Explanation:

Since we have sqrt(4+4) , we can rewrite it as follows:

sqrt(4 * 2)

Now since we have a square root, we have to extract all the squares from within. 4 is a square. The square root of 4 is 2 . So we have:

2sqrt2

2 is not a square, so it can not be reduced any further. So therefore the answer is

2sqrt2
