Question

`3√(2)`

Hope it helps.

Answer 2

`3√(2)`

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:

=
`√(18)`

=
`√(9x2)`

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:

=
`3√(2)`

Hope this helps!
