3sqrt2

Explanation:

First put change the words into an equation:
sqrt3 xx sqrt6

Now you can multiply them together as you would normally multiply:
sqrt3 xx sqrt6 = sqrt18

Now let's prime factor 18 and see if there are any squares that we can take out of it to simplify. All we have to see is if there are 2 numbers that are the same:
" " " "18
" " " / \ "
" " "6 " " 3 "
" / \ "
" 2 " 3"

As you can see, we have a square: 3 xx 3= 9

So take sqrt9 out of sqrt18. You should have:
sqrt9sqrt2

But since sqrt9 = 3 we can simplify further to make:
sqrt9sqrt2 rarr 3sqrt2

3root 2 or root 18

Explanation:

the answer is 3 root2 because the factors of root 18 are 2 and 9 and since 9 is a perfect square you can take it out of the radican and it becomes 3 root2 . Another thing you can do is root18 because when you multiply root3 * root6 you get root18
