It's pretty simple, actually: 6√5−2√5=4√5

Explanation:

What we can do, is we can create a variable for the √5 and then substitute back after we do the math.

Let's say x can be equal to √5. So then our simplified question would read: 6x−2x when we place x in for the √5.

6x−2x=4x so then we just take the √5 and place it back in for the x and we get 4√5.
