$30 \sqrt{ 2 }$
Calculate the value
$\sqrt{ \color{#FF6800}{ 59 } ^ { \color{#FF6800}{ 2 } } - 41 ^ { 2 } }$
$ $ Calculate power $ $
$\sqrt{ \color{#FF6800}{ 3481 } - 41 ^ { 2 } }$
$\sqrt{ 3481 - \color{#FF6800}{ 41 } ^ { \color{#FF6800}{ 2 } } }$
$ $ Calculate power $ $
$\sqrt{ 3481 - \color{#FF6800}{ 1681 } }$
$\sqrt{ \color{#FF6800}{ 3481 } \color{#FF6800}{ - } \color{#FF6800}{ 1681 } }$
$ $ Subtract $ 1681 $ from $ 3481$
$\sqrt{ \color{#FF6800}{ 1800 } }$
$\sqrt{ \color{#FF6800}{ 1800 } }$
$ $ Organize the part that can be taken out of the radical sign inside the square root symbol $ $
$\color{#FF6800}{ 30 } \sqrt{ \color{#FF6800}{ 2 } }$
