Question 1057035
{{{-2/sqrt(2-sqrt(3))}}}

= {{{(-2*(sqrt(2-sqrt(3))))/((sqrt(2-sqrt(3)))*(sqrt(2-sqrt(3)))) }}}
= {{{(-2*(sqrt(2-sqrt(3))))/(2-sqrt(3)) }}}
= {{{ (-2*(sqrt(2-sqrt(3)))*(2+sqrt(3))) / ((2-sqrt(3))*(2+sqrt(3))) }}}
=  {{{ (-2*(sqrt(2-sqrt(3)))*(2+sqrt(3))) / (4+2*sqrt(3)-2*sqrt(3)-3) }}}
  (denominator is 1)
=  {{{ (-2*(sqrt(2-sqrt(3)))*(2+sqrt(3))) }}}
