Answer 2

we are given

`√(18)`

Firstly, we will find all possible factors of 18

`18=2*3*3`

we can also write as

`18=2*3^2`

now, we can plug back

`√(18)=√(2*3^2)`

now, we can use property of exponent

`√(a*b)=√(a)*√(b)`

`√(18)=√(2)*√(3^2)`

now, we can simplify it

`√(18)=√(2)*3`

`√(18)=3√(2)`...............Answer
