Question

pls be qiuck and ans this

Answer 1

Answer:

$\sqrt{22+ 4\sqrt{10} }$  =  $\sqrt{22 + 2\sqrt{40} }$

Using Factorisation way,

$\sqrt{22+2\sqrt{20} \sqrt{2} }$

$\sqrt{\sqrt{20} ^{2}+\sqrt{2} ^{2} + 2 \sqrt{20}\sqrt{2} }$

$\sqrt{(\sqrt{20}+\sqrt{2} )^{2} }$

$(\sqrt{20}+\sqrt{2} )$ is the answer

It took a lot of effort.
