Question

100 POINTS pleasee i need help and explain too

Answer 1

`(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.

Answer 2

The answer is b to be sure
