$a ^ { 2 }$
Organize polynomials
$\color{#FF6800}{ a } \color{#FF6800}{ a }$
$ $ Arrange the variable part of the mononomial expression $ $
$\color{#FF6800}{ a } ^ { \color{#FF6800}{ 2 } }$
$a ^ { 2 }$
Organize using the law of exponent
$\color{#FF6800}{ a } a$
$ $ If the exponent is omitted, the exponent of that term is equal to 1 $ $
$\color{#FF6800}{ a } ^ { \color{#FF6800}{ 1 } } a$
$a ^ { 1 } \color{#FF6800}{ a }$
$ $ If the exponent is omitted, the exponent of that term is equal to 1 $ $
$a ^ { 1 } \color{#FF6800}{ a } ^ { \color{#FF6800}{ 1 } }$
$\color{#FF6800}{ a } ^ { \color{#FF6800}{ 1 } } \color{#FF6800}{ a } ^ { \color{#FF6800}{ 1 } }$
$ $ Add the exponent as the base is the same $ $
$\color{#FF6800}{ a } ^ { \color{#FF6800}{ 1 } \color{#FF6800}{ + } \color{#FF6800}{ 1 } }$
$a ^ { \color{#FF6800}{ 1 } \color{#FF6800}{ + } \color{#FF6800}{ 1 } }$
$ $ Add $ 1 $ and $ 1$
$a ^ { \color{#FF6800}{ 2 } }$
