Calculate the value
$\color{#FF6800}{ 3 } ^ { \color{#FF6800}{ 8 } } \color{#FF6800}{ + } \color{#FF6800}{ 3 } ^ { \color{#FF6800}{ 8 } } \color{#FF6800}{ + } \color{#FF6800}{ 3 } ^ { \color{#FF6800}{ 8 } }$
$ $ Add the forms of the powers with the same bases and exponents $ $
$\color{#FF6800}{ 3 } \color{#FF6800}{ \times } \color{#FF6800}{ 3 } ^ { \color{#FF6800}{ 8 } }$
$\color{#FF6800}{ 3 } \color{#FF6800}{ \times } \color{#FF6800}{ 3 } ^ { \color{#FF6800}{ 8 } }$
$ $ Simplify the expression $ $
$\color{#FF6800}{ 19683 }$
