Question

Solve: $\left(\sqrt{2}\times \sqrt{2}\times \sqrt{2}\times \sqrt{2}\times \sqrt{2}\right)\times \sqrt{2}$
$\stackrel{\downarrow }{5\sqrt{2}}$

Answer 1

$(\sqrt{2}+\sqrt{2}+\sqrt{2}+\sqrt{2}+\sqrt{2})\times \sqrt{2}$

$\to (2\sqrt{2}+\sqrt{2}+\sqrt{2}+\sqrt{2})\times \sqrt{2}$

$\to \left(5\sqrt{2}\right)\times \sqrt{2}$

$\to 5\times \sqrt{2}\times \sqrt{2}$

$\to 5\times 2$

$\Rightarrow 10$
