Calculate the value

Answer

$2 ^{ -1 }$

$\dfrac { 1 } { 2 }$

Calculate the value

$2 ^ { \color{#FF6800}{ - } \color{#FF6800}{ 1 } }$

$ $ If the exponent is negative, change it to a fraction $ $

$\dfrac { 1 } { 2 ^ { 1 } }$

$\dfrac { 1 } { 2 ^ { \color{#FF6800}{ 1 } } }$

$ $ If the exponent is 1, get rid of it as it is unnecessary $ $

$\dfrac { 1 } { 2 }$
