Question

Como simplificar ???????
$\sqrt{2000} + \sqrt{200} + \sqrt{20 } + \sqrt{2}$

Answer 1

$\sqrt{2000} + \sqrt{200} + \sqrt{20} + \sqrt{2}$
 $\sqrt{5. 20^{2} } + \sqrt{2. 10^{2} } + \sqrt{5. 2^{2} } + \sqrt{2}$
$20 \sqrt{5} + 10 \sqrt{2} + 2 \sqrt{5} + \sqrt{2}$
$(20+2) \sqrt{5} + (10+1) \sqrt{2}$
$22 \sqrt{5} + 11 \sqrt{2}$
