Question

plzz explain this answer: (whoever explains correctly will be marked brainliest)

Answer 1

$Given : \sqrt{3 - 2 \sqrt{2} }$

It can be written as

$\sqrt{ \sqrt{2}^2 - 2 \sqrt{2} + 1 }$

$\sqrt{( \sqrt{2}^2 - \sqrt{2} ) + (- \sqrt{2} + 1) }$

$\sqrt{ \sqrt{2}( \sqrt{2} - 1) - 1 ( \sqrt{2} - 1 ) }$

$\sqrt{( \sqrt{2} - 1)( \sqrt{2} - 1) }$

$\sqrt{( \sqrt{2} - 1)^2 }$

$\sqrt{2} - 1$


Hope this helps!
