This is easier than it may appear. To find the square root of a fraction, you simply have to find the square root of the numerator and denominator separately. In this problem, that just means finding the square root of 1 and the square root of 25. √1 = 1 since 1•1=1 √25 = 5 since 5•5=25. So the square root of 1/25 is 1/5. Checking your work you can multiply 1/5 by 1/5 to be sure. 1/5 • 1/5 = 1/25 so that confirms this is the correct answer.
