2sqrt2 22

Explanation:

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

sqrt(4 * 2) 42

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

2sqrt2 22

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

2sqrt2 22
