Formula
Calculate the value
$$\left ( - \dfrac { 1 } { 2 } \right ) ^ { 2 }$$
$\dfrac { 1 } { 4 }$
Calculate the value
$\left ( \color{#FF6800}{ - } \color{#FF6800}{ \dfrac { \color{#FF6800}{ 1 } } { \color{#FF6800}{ 2 } } } \right ) ^ { \color{#FF6800}{ 2 } }$
 Remove negative signs because negative numbers raised to even powers are positive 
$\left ( \dfrac { 1 } { 2 } \right ) ^ { 2 }$
$\left ( \color{#FF6800}{ \dfrac { \color{#FF6800}{ 1 } } { \color{#FF6800}{ 2 } } } \right ) ^ { \color{#FF6800}{ 2 } }$
 When raising a fraction to the power, raise the numerator and denominator each to the power 
$\dfrac { \color{#FF6800}{ 1 } ^ { \color{#FF6800}{ 2 } } } { \color{#FF6800}{ 2 } ^ { \color{#FF6800}{ 2 } } }$
$\dfrac { \color{#FF6800}{ 1 } ^ { \color{#FF6800}{ 2 } } } { 2 ^ { 2 } }$
 Calculate power 
$\dfrac { \color{#FF6800}{ 1 } } { 2 ^ { 2 } }$
$\dfrac { 1 } { \color{#FF6800}{ 2 } ^ { \color{#FF6800}{ 2 } } }$
 Calculate power 
$\dfrac { 1 } { \color{#FF6800}{ 4 } }$
