#3sqrt2#

Explanation:

#sqrt(a^2b)=asqrtb rarr# We can take out perfect squares from inside radicals

#sqrt18=sqrt(9*2) rarr 9# is a perfect square

#3sqrt2#

To find perfect squares, you can start by listing out factors of #18# and seeing if any are perfect squares.

You could also find the prime factorization and see if any two numbers are being multiplied together (the prime factorization for #18# is #3*3*2# and there are two #3#'s).
