Question

What is the following product √30 * √10

2√10

3√10

4√10

10√3

Answer 1

Answer:

10√3

Explanation:

Let's rewrite the expression. We have:

$\sqrt{30} \cdot \sqrt{10}$

we can write 30 as $3\cdot 10$, so we have

$\sqrt{3 \cdot 10} \cdot \sqrt{10}$

which is equal to

$\sqrt{3 \cdot 10 \cdot 10}=\sqrt{3 \cdot 100}$

but $\sqrt{100}=10$, so we have

$\sqrt{3 \cdot 100}=\sqrt{3} \sqrt{100}=\sqrt{3} \cdot 10=10 \sqrt{3}$
