Find the number of divisors
$\color{#FF6800}{ 19 } \color{#FF6800}{ \times } \color{#FF6800}{ 19 }$
$ $ Do prime factorization $ $
$\color{#FF6800}{ 19 } \color{#FF6800}{ \times } \color{#FF6800}{ 19 }$
$\color{#FF6800}{ 19 } \times 19$
$ $ If the exponent is omitted, the exponent of that term is equal to 1 $ $
$\color{#FF6800}{ 19 } ^ { \color{#FF6800}{ 1 } } \times 19$
$19 ^ { 1 } \times \color{#FF6800}{ 19 }$
$ $ If the exponent is omitted, the exponent of that term is equal to 1 $ $
$19 ^ { 1 } \times \color{#FF6800}{ 19 } ^ { \color{#FF6800}{ 1 } }$
$\color{#FF6800}{ 19 } ^ { \color{#FF6800}{ 1 } } \times \color{#FF6800}{ 19 } ^ { \color{#FF6800}{ 1 } }$
$ $ Add the exponent as the base is the same $ $
$\color{#FF6800}{ 19 } ^ { \color{#FF6800}{ 1 } \color{#FF6800}{ + } \color{#FF6800}{ 1 } }$
$19 ^ { \color{#FF6800}{ 1 } \color{#FF6800}{ + } \color{#FF6800}{ 1 } }$
$ $ Add $ 1 $ and $ 1$
$19 ^ { \color{#FF6800}{ 2 } }$
$\color{#FF6800}{ 19 } ^ { \color{#FF6800}{ 2 } }$
$ $ Find the number of divisors using an exponent $ $
$\color{#FF6800}{ 3 }$
