Answer:

It should be 9√3

Ana probably got confused about the difference between square root and cube root.

Step-by-step explanation:

To get the square root of 27, factor it as √9*3 Then pull out the square root of 9 which is 3. So you are left with 3√3.

That is=5.196152423

Then multiply (3)(3√3) to get 9√3 which is 15.58845727
