$9sqrt2$

First, notice that $sqrt9=3$ , since $3^2=9$ .

So, the expression more simply becomes:

$3xx3sqrt2$

Recall that $3sqrt2$ is just a multiplication problem between $3$ and $sqrt2$ , that is, $3sqrt2=3xxsqrt2$ .

Hence the expression can be written as

$3xx3xxsqrt2$

We can simplify $3xx3=9$ . We cannot do anything with the $sqrt2$ , so our final answer is

$9sqrt2$
