They're both to the same exponent, so you can divide out an x. Then you get 25/x^2 all under a square root. Then it's just the square root of each individually, so you get 5/x.
[Remember, when you have numbers being multiplied under a square root, you can treat them as either being put to the power individually, or you can multiply/divide them first and then put the result to the power. Square root is 1/2 as an exponent.]
