$900$
Calculate the value
$\color{#FF6800}{ 29 } ^ { \color{#FF6800}{ 2 } } + 2 \times 29 + 1$
$ $ Calculate power $ $
$\color{#FF6800}{ 841 } + 2 \times 29 + 1$
$841 + \color{#FF6800}{ 2 } \color{#FF6800}{ \times } \color{#FF6800}{ 29 } + 1$
$ $ Multiply $ 2 $ and $ 29$
$841 + \color{#FF6800}{ 58 } + 1$
$\color{#FF6800}{ 841 } \color{#FF6800}{ + } \color{#FF6800}{ 58 } \color{#FF6800}{ + } \color{#FF6800}{ 1 }$
$ $ Find the sum $ $
$\color{#FF6800}{ 900 }$
$900$
Calculation using the perfect square formula
$29 ^ { 2 } + 2 \times 29 + \color{#FF6800}{ 1 }$
$ $ Present as the shape of the power $ $
$29 ^ { 2 } + 2 \times 29 + \color{#FF6800}{ 1 } ^ { \color{#FF6800}{ 2 } }$
$29 ^ { 2 } + \color{#FF6800}{ 2 } \color{#FF6800}{ \times } \color{#FF6800}{ 29 } + 1 ^ { 2 }$
$ $ Change the term in the middle $ $
$29 ^ { 2 } + \color{#FF6800}{ 2 } \color{#FF6800}{ \times } \color{#FF6800}{ 29 } \color{#FF6800}{ \times } \color{#FF6800}{ 1 } + 1 ^ { 2 }$
$\color{#FF6800}{ 29 } ^ { \color{#FF6800}{ 2 } } \color{#FF6800}{ + } \color{#FF6800}{ 2 } \color{#FF6800}{ \times } \color{#FF6800}{ 29 } \color{#FF6800}{ \times } \color{#FF6800}{ 1 } \color{#FF6800}{ + } \color{#FF6800}{ 1 } ^ { \color{#FF6800}{ 2 } }$
$ $ Organize the expression using $ A^{2} ± 2AB + B^2 = (A ± B)^{2}$
$\left ( \color{#FF6800}{ 29 } \color{#FF6800}{ + } \color{#FF6800}{ 1 } \right ) ^ { \color{#FF6800}{ 2 } }$
$\left ( \color{#FF6800}{ 29 } \color{#FF6800}{ + } \color{#FF6800}{ 1 } \right ) ^ { 2 }$
$ $ Add $ 29 $ and $ 1$
$\color{#FF6800}{ 30 } ^ { 2 }$
$\color{#FF6800}{ 30 } ^ { \color{#FF6800}{ 2 } }$
$ $ Calculate power $ $
$\color{#FF6800}{ 900 }$
