Answer:


(3 √(5) )/(10)

Explanation:

Given the expression:


(3 √(20) )/(5 √(16) )

The expression can be written in the form below:


= (3 √(4 * 5) )/(5 √(4 * 4) )

Simplify further:


= \frac{3 * \sqrt{4 * √(5) } }{5 * 4} \\ = (3 * 2 * √(5) )/(5 * 4) \\ = (6 √(5) )/(20) \\ = (3 √(5) )/(10)

The correct choice is B.
