x=√13 + 2√3
x-1/x=?
=√13 + 2√3 - 1/√13 + 2√3
=(√13 + 2√3)²-1]/√13 + 2√3
=[ √13² + (2√3)² + 2(√13 )(2√3)- 1 ]/√13 + 2√3
=13+4×3+4√39 -1 / √13 + 2√3
=( 24 + 4√39 )  / (√13 + 2√3 ) ans

Solution:-

x =  \sqrt{13}  + 2 \sqrt{3}  \\ x -  \frac{1}{x}  =  \sqrt{13 }  + 2 \sqrt{3}  -  \frac{1}{ \sqrt{13}  + 2 \sqrt{3} }  \\  \frac{13 + 12 + 4 \sqrt{39} }{ \sqrt{13}  + 2 \sqrt{3} }  \\  \frac{23 + 4 \sqrt{39} }{ \sqrt{13}  + 2 \sqrt{3} }  \times   \frac{ \sqrt{13} - 2 \sqrt{3}  }{ \sqrt{13} - 2 \sqrt{3}  }  \\  \frac{23 \sqrt{13}  + 4 \sqrt{507}  - 46 \sqrt{3} - 8 \sqrt{117}  }{13 - 12}  \\ 23 \sqrt{13}  + 52 \sqrt{3}  - 46 \sqrt{3}  - 24 \sqrt{13}  \\( 6 \sqrt{3}  -  \sqrt{13} )ans
