Mathematics

$\sqrt{4}\cdot \sqrt{15}=2\sqrt{15}$

Step-by-step explanation:

We have been given a radical expression $\sqrt{60}$ . We are asked to rewrite the given radicand as two factors, one of which is a perfect square.

We can rewrite 60 as product of 4 and 15 as:

$\sqrt{4*15}$

Using property $\sqrt{m} \cdot \sqrt{n} =\sqrt{m\cdot n}$ we will get,

$\sqrt{4}\cdot \sqrt{15}$

Since 4 is a perfect square, so we can simplify our expression as:

$2\cdot \sqrt{15}$ .
