Calculate the value
$\left ( \color{#FF6800}{ - } \sqrt{ \color{#FF6800}{ 9 } } \right ) ^ { \color{#FF6800}{ 2 } } - \left ( - \sqrt{ 5 } \right ) ^ { 2 } - \sqrt{ \left ( - 2 \right ) ^ { 2 } }$
$ $ Remove negative signs because negative numbers raised to even powers are positive $ $
$\left ( \sqrt{ 9 } \right ) ^ { 2 } - \left ( - \sqrt{ 5 } \right ) ^ { 2 } - \sqrt{ \left ( - 2 \right ) ^ { 2 } }$
$\left ( \sqrt{ \color{#FF6800}{ 9 } } \right ) ^ { \color{#FF6800}{ 2 } } - \left ( - \sqrt{ 5 } \right ) ^ { 2 } - \sqrt{ \left ( - 2 \right ) ^ { 2 } }$
$ $ If you square the radical sign, it will disappear $ $
$\color{#FF6800}{ 9 } - \left ( - \sqrt{ 5 } \right ) ^ { 2 } - \sqrt{ \left ( - 2 \right ) ^ { 2 } }$
$9 - \left ( \color{#FF6800}{ - } \sqrt{ \color{#FF6800}{ 5 } } \right ) ^ { \color{#FF6800}{ 2 } } - \sqrt{ \left ( - 2 \right ) ^ { 2 } }$
$ $ Remove negative signs because negative numbers raised to even powers are positive $ $
$9 - \left ( \sqrt{ 5 } \right ) ^ { 2 } - \sqrt{ \left ( - 2 \right ) ^ { 2 } }$
$9 - \left ( \sqrt{ \color{#FF6800}{ 5 } } \right ) ^ { \color{#FF6800}{ 2 } } - \sqrt{ \left ( - 2 \right ) ^ { 2 } }$
$ $ If you square the radical sign, it will disappear $ $
$9 - \color{#FF6800}{ 5 } - \sqrt{ \left ( - 2 \right ) ^ { 2 } }$
$9 - 5 - \sqrt{ \left ( - 2 \right ) ^ { \color{#FF6800}{ 2 } } }$
$ $ Organize as the power is written in the radical sign, and the root exponent and the exponent are the same $ $
$9 - 5 - \color{#FF6800}{ 2 }$
$\color{#FF6800}{ 9 } \color{#FF6800}{ - } \color{#FF6800}{ 5 } \color{#FF6800}{ - } \color{#FF6800}{ 2 }$
$ $ Calculate the sum or the difference $ $
$\color{#FF6800}{ 2 }$
