I am assuming that you are implying the following:
11√2
-----
2
If this is what you mean, then no it cannot be simplified any further. The two's do not cancel each other out due to the square root symbol above the one in the numerator. So the answer you provided is simplified.

76
The square root of 60 is the square root of 2 x 2 x 3 x 5. When that is simplified, a 2 comes out from under the radical sign, resulting in a final answer of 2 radical 15.
2
First, note that radical 4 is 2. So 3xradical 4 is just 6, Now we have 6+2 radical 3. You can't do much with this except factor out a 2 if you want 2(3+Radical 3)
2√11

√44 = √(4 x 11) = √(22 x 11) = 2√11.
1 over 2 times radical 6
12 radical 2
2 radical(8) = 4 radical(2)
2/11 cannot be simplified further.
5 radical 2 (5√2)
4 radical 6
There is no radical to simplify!
