11sqrt2 - 2

Explanation:

Before we begin tackling this problem, separate it into small chunks so that it is easier for us to handle.

sqrt-4 does not exist as it is a negative surd(radical) so the problem looks like this.

3sqrt2*(2) = 6sqrt2

sqrt2(5-sqrt2)
Multiply it out and then simplify:

5sqrt2-sqrt4 = 5sqrt2 - 2

Now add the two parts together which will give you the answer.

6sqrt2 + 5sqrt2 - 2

= 11sqrt2 - 2
