Calculate the value

Answer

$- \sqrt{ 0.2 ^{ 2 } }$

$- \dfrac { 1 } { 5 }$

Calculate the value

$- \sqrt{ 0.2 ^ { \color{#FF6800}{ 2 } } }$

$ $ Organize as the power is written in the radical sign, and the root exponent and the exponent are the same $ $

$- \color{#FF6800}{ 0.2 }$

$\color{#FF6800}{ - } \color{#FF6800}{ 0.2 }$

$ $ Convert decimals to fractions $ $

$\color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 1 } { 5 } }$
