Answer:

Step-by-step explanation:
Hi!
This is a lot of radicals, so it may seem tricky. Let's begin by simplifying all of the radicals that can be simplified.
We can see that
can be simplified.
Taking prime factorization:

which is:

So an updated equation is
.
Now, we need to expand this:
First, let's expand the parenthesis:
.
We can apply some of are rules:

And, now to simplifying!
Adding similar elements:

Simplifying and cleaning up each radical:
.
Now all we have to do is add the similar elements (again.)
In doing so we reach an answer of 
Hope this helps!
