$\left( \sqrt{ 2 } +1 \right) ^{ 2 } + \left( \sqrt{ 2 } -1 \right) ^{ 2 }$
$6$
Calculate the value
$\left ( \sqrt{ \color{#FF6800}{ 2 } } \color{#FF6800}{ + } \color{#FF6800}{ 1 } \right ) ^ { \color{#FF6800}{ 2 } } + \left ( \sqrt{ 2 } - 1 \right ) ^ { 2 }$
$ $ Calculate power $ $
$\color{#FF6800}{ 2 } \sqrt{ \color{#FF6800}{ 2 } } + \color{#FF6800}{ 3 } + \left ( \sqrt{ 2 } - 1 \right ) ^ { 2 }$
$2 \sqrt{ 2 } + 3 + \left ( \sqrt{ \color{#FF6800}{ 2 } } \color{#FF6800}{ - } \color{#FF6800}{ 1 } \right ) ^ { \color{#FF6800}{ 2 } }$
$ $ Calculate power $ $
$2 \sqrt{ 2 } + 3 + \color{#FF6800}{ 3 } \color{#FF6800}{ - } \color{#FF6800}{ 2 } \sqrt{ \color{#FF6800}{ 2 } }$
$\color{#FF6800}{ 2 } \sqrt{ \color{#FF6800}{ 2 } } + 3 + 3 \color{#FF6800}{ - } \color{#FF6800}{ 2 } \sqrt{ \color{#FF6800}{ 2 } }$
$ $ Eliminate opponent number $ $
$3 + 3$
$\color{#FF6800}{ 3 } \color{#FF6800}{ + } \color{#FF6800}{ 3 }$
