Answer:
The first one is your answer.
Step-by-step explanation:
What you do is you have to look at the 2/18 in the square root. That can come out to be 1/3. So you know that a 3 is going to be on the bottom.
Now you look at the x^5. What you do is you make it until you have 5 x's like this x, x, x, x, x. You then put them in pairs of two.
x,x x,x x. There are two pairs of two so that comes out.
So you have 1x^2sqrtx/3. which is the first one.
#1 is your answer.
