$\left( 2- \sqrt{ 3 } -2 \right) ^{ 2 }$
$3$
Calculate the value
$\left ( \color{#FF6800}{ 2 } - \sqrt{ 3 } \color{#FF6800}{ - } \color{#FF6800}{ 2 } \right ) ^ { 2 }$
$ $ Remove the two numbers if the values are the same and the signs are different $ $
$\left ( - \sqrt{ 3 } \right ) ^ { 2 }$
$\left ( \color{#FF6800}{ - } \sqrt{ \color{#FF6800}{ 3 } } \right ) ^ { \color{#FF6800}{ 2 } }$
$ $ Remove negative signs because negative numbers raised to even powers are positive $ $
$\left ( \sqrt{ 3 } \right ) ^ { 2 }$
$\left ( \sqrt{ \color{#FF6800}{ 3 } } \right ) ^ { \color{#FF6800}{ 2 } }$
$ $ If you square the radical sign, it will disappear $ $
$\color{#FF6800}{ 3 }$
