$\dfrac { 1 } { 64 }$
Calculate the value
$2 ^ { \color{#FF6800}{ - } \color{#FF6800}{ 6 } }$
$ $ If the exponent is negative, change it to a fraction $ $
$\dfrac { 1 } { 2 ^ { 6 } }$
$\dfrac { 1 } { \color{#FF6800}{ 2 } ^ { \color{#FF6800}{ 6 } } }$
$ $ Calculate power $ $
$\dfrac { 1 } { \color{#FF6800}{ 64 } }$
