Answer:
The correct answer is [tex]\frac{\sqrt{5} }{4}[/tex]
Step-by-step explanation:
When simplifying a fraction in a square root the square root can be applied to both the numerator and the denominator. So [tex]\sqrt{\frac{x}{y} }[/tex] is equal to [tex]\frac{\sqrt{x} }{\sqrt{y} }[/tex] . In this problem, the square root of 5 is just [tex]\sqrt{5}[/tex], and the square root of 16 is [tex]\sqrt{16}[/tex], which is equal to 4.
Hope this helps!
