Im so lost what the answer is

Answer:
Unfortunately, we can't do anything with 41 as it has no factors. Since [tex]3\sqrt{41}[/tex] is already simplified, try submitting that as your answer. If that doesn't work then try un-doing their steps and get rid of the 3:
[tex]3\sqrt{41}[/tex]
[tex]\sqrt{41(9)}[/tex]
[tex]\sqrt{369}[/tex]
Hope this helps!
