circle-check-icon
$\dfrac{ \left( \sqrt{ 2 } -1 \right) ^{ 2 } }{ \left( \sqrt{ 2 } \right) ^{ 2 } -1 ^{ 2 } }$
$3 - 2 \sqrt{ 2 }$
Calculate the value
$\dfrac { \left ( \sqrt{ \color{#FF6800}{ 2 } } \color{#FF6800}{ - } \color{#FF6800}{ 1 } \right ) ^ { \color{#FF6800}{ 2 } } } { \left ( \sqrt{ 2 } \right ) ^ { 2 } - 1 ^ { 2 } }$
$ $ Calculate power $ $
$\dfrac { \color{#FF6800}{ 3 } \color{#FF6800}{ - } \color{#FF6800}{ 2 } \sqrt{ \color{#FF6800}{ 2 } } } { \left ( \sqrt{ 2 } \right ) ^ { 2 } - 1 ^ { 2 } }$
$\dfrac { 3 - 2 \sqrt{ 2 } } { \left ( \sqrt{ \color{#FF6800}{ 2 } } \right ) ^ { \color{#FF6800}{ 2 } } - 1 ^ { 2 } }$
$ $ If you square the radical sign, it will disappear $ $
$\dfrac { 3 - 2 \sqrt{ 2 } } { \color{#FF6800}{ 2 } - 1 ^ { 2 } }$
$\dfrac { 3 - 2 \sqrt{ 2 } } { 2 - \color{#FF6800}{ 1 } ^ { \color{#FF6800}{ 2 } } }$
$ $ Calculate power $ $
$\dfrac { 3 - 2 \sqrt{ 2 } } { 2 - \color{#FF6800}{ 1 } }$
$\dfrac { 3 - 2 \sqrt{ 2 } } { \color{#FF6800}{ 2 } \color{#FF6800}{ - } \color{#FF6800}{ 1 } }$
$ $ Subtract $ 1 $ from $ 2$
$\dfrac { 3 - 2 \sqrt{ 2 } } { \color{#FF6800}{ 1 } }$
$\dfrac { 3 - 2 \sqrt{ 2 } } { \color{#FF6800}{ 1 } }$
$ $ If the denominator is 1, the denominator can be removed $ $
$\color{#FF6800}{ 3 } \color{#FF6800}{ - } \color{#FF6800}{ 2 } \sqrt{ \color{#FF6800}{ 2 } }$
