It's pretty simple, actually: 6sqrt5- 2sqrt5=4sqrt5

Explanation:

What we can do, is we can create a variable for the sqrt5 and then substitute back after we do the math.

Let's say x can be equal to sqrt5. So then our simplified question would read: 6x-2x when we place x in for the sqrt5.

6x-2x=4x so then we just take the sqrt5 and place it back in for the x and we get 4sqrt5.
