Answer 2

Answer:

 $\sqrt{10}$ × $\sqrt{15}$ is equal to 5$\sqrt{6}$.

Step-by-step explanation:

Explanation:

Given that, $\sqrt{10}$ × $\sqrt{15}$

$\sqrt{10}$ can be written as $\sqrt{2}$ × $\sqrt{5}$ and

$\sqrt{15}$ can be written as, $\sqrt{3}$ × $\sqrt{5}$.

Therefore, $\sqrt{10}$ × $\sqrt{15}$ can be written as,

⇒ $\sqrt{2}$ ×$\sqrt{5}$ × $\sqrt{3}$ ×$\sqrt{5}$

Now, as we know, product $\sqrt{a}$  and $\sqrt{a}$ = a.

∴ Here we can see that there are two $\sqrt{5}$.

⇒Product of $\sqrt{5} and \sqrt{5}$ = 5.

∴ $\sqrt{2}$ ×$\sqrt{5}$ × $\sqrt{3}$ ×$\sqrt{5}$ = 5 ($\sqrt{2}$ × $\sqrt{3}$ ) = 5$\sqrt{6}$

Final answer:

Hence,  $\sqrt{10}$ × $\sqrt{15}$ is equal to 5$\sqrt{6}$.
