$\sqrt{ 63 }$
$3 \sqrt{ 7 }$
Find the square root
$\sqrt{ \color{#FF6800}{ 63 } }$
$ $ Do a factorization in prime factors for the integral number inside the radical sign $ $
$\sqrt{ \color{#FF6800}{ 3 } ^ { \color{#FF6800}{ 2 } } \color{#FF6800}{ \times } \color{#FF6800}{ 7 } }$
$\sqrt{ \color{#FF6800}{ 3 } ^ { \color{#FF6800}{ 2 } } \times 7 }$
$ $ Separate the part that can be taken out of radical sign to different radical sign from the prime factor to the prime factor $ $
$\sqrt{ \color{#FF6800}{ 3 } ^ { \color{#FF6800}{ 2 } } } \sqrt{ 7 }$
$\sqrt{ \color{#FF6800}{ 3 } ^ { \color{#FF6800}{ 2 } } } \sqrt{ 7 }$
$ $ Get rid of the radical sign and change it to the denominator of the exponent $ $
$\color{#FF6800}{ 3 } ^ { \color{#FF6800}{ \frac { 2 } { 2 } } } \sqrt{ 7 }$
$3 ^ { \color{#FF6800}{ \frac { 2 } { 2 } } } \sqrt{ 7 }$
$ $ Reduce the fraction to the lowest term $ $
$3 ^ { \color{#FF6800}{ 1 } } \sqrt{ 7 }$
$3 ^ { \color{#FF6800}{ 1 } } \sqrt{ 7 }$
$ $ If the exponent is 1, get rid of it as it is unnecessary $ $
$3 \sqrt{ 7 }$
$\approx 7.9373$
Find the approximate value
$\sqrt{ \color{#FF6800}{ 63 } }$
$ $ Find the approximate value of the square root $ $
$\approx \color{#FF6800}{ 7.9373 }$
