Answer 2

Answer:

$\sqrt{13} +2\sqrt{10}-\sqrt{7}$

Step-by-step explanation:

To evaluate:

$\sqrt{13} +4\sqrt{10} -\sqrt{7} -2\sqrt{10}$

Add the terms which have same radicals expression:

$\sqrt{13} +(4\sqrt{10}-2\sqrt{10})-\sqrt{7}$

Simplify:

$\sqrt{13} +(2\sqrt{10})-\sqrt{7}$

or

$\sqrt{13} +2\sqrt{10}-\sqrt{7}$

Therefore, the simplified expression of $\sqrt{13} +4\sqrt{10} -\sqrt{7} -2\sqrt{10}$ is, $\sqrt{13} +2\sqrt{10}-\sqrt{7}$
