A. 25/4
B. 2√3/15
C. √5/5
D. 6

Answer 1

I'm assuming you meant (3√20) /√5, (make sure you put parenthesis, or else it looks like it was 3 (√20 /√5)).


In this case, the answer would be 6! Have a great day!!  

Answer 2

After the simplification the given expression $\frac{3\sqrt{20} }{\sqrt{5} }$ becomes 6.

What is the simplification of an expression?

Simplifying expressions is a way to write an expression in its lowest form by combining all like terms together.

According to the given question.

We have an expression

$\frac{3\sqrt{20} }{\sqrt{5} }$

The simplified form of the above expression is given by

$\frac{3\sqrt{20} }{\sqrt{5} } \\= \frac{3\sqrt{4(5)} }{\sqrt{5} }$                       (because $\sqrt{4} =\sqrt{2(2)} =2$)

$=\frac{3(2)\sqrt{5} } {\sqrt{5} }$

$= 6$

Hence, $\frac{3\sqrt{20} }{\sqrt{5} } =6$

Thus, option D is correct.
