Answer 2

Answer:

$10\sqrt{5}$

Step-by-step explanation:

The given equation is:

$9\sqrt{5}-4\sqrt{5}+\sqrt{125}$

On solving this, we get

$9\sqrt{5}-4\sqrt{5}+5\sqrt{5}$

Taking $\sqrt{5}$ common from all the terms, we get

$\sqrt{5}(9-4+5)$

$\sqrt{5}(5+5)$

$10\sqrt{5}$

which is the required simplified form.
