Question

evaluate root5 +root2 +(root 8+ root 5 )^2​

Answer 1

Answer:

$\sqrt{5}+\sqrt{2}+\left(\sqrt{8}+\sqrt{5}\right)^2$

$\sqrt{5}+\sqrt{2}+\left[(\sqrt{8})^2+2(\sqrt{8})(\sqrt{5})} +(\sqrt{5}\right)^2]$

$\sqrt{5}+\sqrt{2}+\left[8+2*2(\sqrt{2}\sqrt{5}) +5]$

$\sqrt{5}+\sqrt{2}+\left[8+4\sqrt{2}\sqrt{5} +5]$

$\sqrt{5}+\sqrt{2}+\left[8+4\sqrt{10} +5]$

$\sqrt{5}+\sqrt{2}+\left(13+4\sqrt{10})$

$\sqrt{5}+\sqrt{2}+13+4\sqrt{10}$
