$\left ( \color{#FF6800}{ - } \color{#FF6800}{ i } \right ) ^ { \color{#FF6800}{ 2 } }$
$ $ Remove negative signs because negative numbers raised to even powers are positive $ $
$i ^ { 2 }$
$\color{#FF6800}{ i } ^ { \color{#FF6800}{ 2 } }$
$ $ It is $ i^2 = -1$
$\color{#FF6800}{ - } \color{#FF6800}{ 1 }$
