3sqrt232

Explanation:

First put change the words into an equation:
sqrt3 xx sqrt63×6

Now you can multiply them together as you would normally multiply:
sqrt3 xx sqrt6 = sqrt183×6=18

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 18
" " " / \ " / \
" " "6 " " 3 " 6 3
" / \ " / \
" 2 " 3" 2 3

As you can see, we have a square: 3 xx 3= 93×3=9

So take sqrt99 out of sqrt1818. You should have:
sqrt9sqrt292

But since sqrt9 = 39=3 we can simplify further to make:
sqrt9sqrt2 rarr 3sqrt29232

3root 32 or root 18

Explanation:

the answer is 3 root32 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 root32 . Another thing you can do is root18 because when you multiply root3 * root6 you get root18
