 Find the conjugate irrational number of denominator 
$\color{#FF6800}{ \dfrac { 2 } { \sqrt{ 5 } - \sqrt{ 2 } } } \color{#FF6800}{ \times } \color{#FF6800}{ \dfrac { \sqrt{ 5 } + \sqrt{ 2 } } { \sqrt{ 5 } + \sqrt{ 2 } } }$
$\dfrac { 2 } { \sqrt{ 5 } - \sqrt{ 2 } } \times \dfrac { \sqrt{ 5 } + \sqrt{ 2 } } { \sqrt{ 5 } + \sqrt{ 2 } }$
 The denominator is multiplied by denominator, and the numerator is multiplied by numerator 
$\color{#FF6800}{ \dfrac { 2 \left ( \sqrt{ 5 } + \sqrt{ 2 } \right ) } { \left ( \sqrt{ 5 } - \sqrt{ 2 } \right ) \left ( \sqrt{ 5 } + \sqrt{ 2 } \right ) } }$
$\dfrac { \color{#FF6800}{ 2 } \left ( \sqrt{ \color{#FF6800}{ 5 } } \color{#FF6800}{ + } \sqrt{ \color{#FF6800}{ 2 } } \right ) } { \left ( \sqrt{ 5 } - \sqrt{ 2 } \right ) \left ( \sqrt{ 5 } + \sqrt{ 2 } \right ) }$

$\dfrac { \color{#FF6800}{ 2 } \sqrt{ \color{#FF6800}{ 5 } } \color{#FF6800}{ + } \color{#FF6800}{ 2 } \sqrt{ \color{#FF6800}{ 2 } } } { \left ( \sqrt{ 5 } - \sqrt{ 2 } \right ) \left ( \sqrt{ 5 } + \sqrt{ 2 } \right ) }$
$\dfrac { 2 \sqrt{ 5 } + 2 \sqrt{ 2 } } { \left ( \sqrt{ \color{#FF6800}{ 5 } } \color{#FF6800}{ - } \sqrt{ \color{#FF6800}{ 2 } } \right ) \left ( \sqrt{ \color{#FF6800}{ 5 } } \color{#FF6800}{ + } \sqrt{ \color{#FF6800}{ 2 } } \right ) }$
 Expand the expression using $\left(a - b\right)\left(a + b\right) = a^{2} - b^{2}$
$\dfrac { 2 \sqrt{ 5 } + 2 \sqrt{ 2 } } { \left ( \sqrt{ \color{#FF6800}{ 5 } } \right ) ^ { \color{#FF6800}{ 2 } } \color{#FF6800}{ - } \left ( \sqrt{ \color{#FF6800}{ 2 } } \right ) ^ { \color{#FF6800}{ 2 } } }$
$\dfrac { 2 \sqrt{ 5 } + 2 \sqrt{ 2 } } { \left ( \sqrt{ \color{#FF6800}{ 5 } } \right ) ^ { \color{#FF6800}{ 2 } } - \left ( \sqrt{ 2 } \right ) ^ { 2 } }$
 Calculate power 
$\dfrac { 2 \sqrt{ 5 } + 2 \sqrt{ 2 } } { \color{#FF6800}{ 5 } - \left ( \sqrt{ 2 } \right ) ^ { 2 } }$
