#### Answer:

- Check for factors that are quadratic numbers inside the roots
- Try to make the square roots the same, i.e.
#sqrt(3)# or#sqrt(2)# - Add them together if the square roots have the same value

The answer will be#26sqrt(2)#

#### Explanation:

Let's factorize the numbers inside the square roots.

We can see that we have common factors, let's isolate them!

Working with square roots, we can separate factors in the same square root:

Let's do this with our common factors.

(NOTE: We only want TWO common factors as long as we have a square root).

We already know that

I hope this helped :-)
