Formula
Calculate the value
$\sqrt{ 2 ^{ 2 } } + \left( - \sqrt{ 3 } \right) ^{ 2 } - \sqrt{ \left( -5 \right) ^{ 2 } }$
$0$
Calculate the value
$\sqrt{ 2 ^ { \color{#FF6800}{ 2 } } } + \left ( - \sqrt{ 3 } \right ) ^ { 2 } - \sqrt{ \left ( - 5 \right ) ^ { 2 } }$
 Organize as the power is written in the radical sign, and the root exponent and the exponent are the same 
$\color{#FF6800}{ 2 } + \left ( - \sqrt{ 3 } \right ) ^ { 2 } - \sqrt{ \left ( - 5 \right ) ^ { 2 } }$
$2 + \left ( \color{#FF6800}{ - } \sqrt{ \color{#FF6800}{ 3 } } \right ) ^ { \color{#FF6800}{ 2 } } - \sqrt{ \left ( - 5 \right ) ^ { 2 } }$
 Remove negative signs because negative numbers raised to even powers are positive 
$2 + \left ( \sqrt{ 3 } \right ) ^ { 2 } - \sqrt{ \left ( - 5 \right ) ^ { 2 } }$
$2 + \left ( \sqrt{ \color{#FF6800}{ 3 } } \right ) ^ { \color{#FF6800}{ 2 } } - \sqrt{ \left ( - 5 \right ) ^ { 2 } }$
 If you square the radical sign, it will disappear 
$2 + \color{#FF6800}{ 3 } - \sqrt{ \left ( - 5 \right ) ^ { 2 } }$
$2 + 3 - \sqrt{ \left ( - 5 \right ) ^ { \color{#FF6800}{ 2 } } }$
 Organize as the power is written in the radical sign, and the root exponent and the exponent are the same 
$2 + 3 - \color{#FF6800}{ 5 }$
$\color{#FF6800}{ 2 } \color{#FF6800}{ + } \color{#FF6800}{ 3 } \color{#FF6800}{ - } \color{#FF6800}{ 5 }$
 Calculate the sum or the difference 
$\color{#FF6800}{ 0 }$
