5 is the correct answer. First you had to factor by the numbers, and it gave us, [tex]25=5^2=5*5=25[/tex], or [tex]=5^2[/tex]. Then you apply radical rule, and it gave us, [tex]\sqrt{5^2}=5[/tex], and it gave us the answer is 5 is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
