How do i simplify the square root of 18

Step-by-step explanation:

First figure out, out of all the perfect squares(like 4,9,16,25...) which one is divided by 18, and easy in this case. 9x2 =18

So basically, write it down in the squareroot:

=

=

Now, you know that 3x3=9

(basically squareroot of 3 is 9, so u can simply take it out)

So you can simply take the 3 out and you're left with:

=

Hope this helps!

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
