The square root of a product

When we encounter a root that encompasses the entirety of the product, we can decompose the factors of the products and leave a separate root for each of them. Let's not forget to leave the multiplication sign between the factors we have extracted.

Let's put it this way:
(ab)=ab\sqrt{(a\cdot b)}=\sqrt{a}\cdot\sqrt{b}

Solve the following exercise:

\( \sqrt{30}\cdot\sqrt{1}= \)

Practice more now

Let's look at this in the example

4400\sqrt{4\cdot400}
According to the rule of the root of a product, we can break down the factors and leave the root of each factor separately while maintaining the multiplication operation between them:
We will break it down and obtain:
4400\sqrt{4}\cdot\sqrt{400}
220=402*20=40
