1 (sqrt6 +(sqrt11 +sqrt5))
-------------------------------- = ------------------------------------------------------------------- =
(sqrt6 -(sqrt11 +sqrt5)) (sqrt6 -(sqrt11 +sqrt5)) *(sqrt6 +(sqrt11 +sqrt5))
(sqrt6 +(sqrt11 +sqrt5)) sqrt6 +sqrt11 + sqrt5
= ------------------------------------- = ------------------------------------------ =
6 -(sqrt11 +sqrt5)^2 (6 -(11 +2sqrt11 *sqrt5 +5)
sqrt6 +sqrt11 +sqrt5 (sqrt6 +sqrt11 +sqrt5)(10 -2sqrt55)
= --------------------------------- = - -------------------------------------------------- =
- 10 - 2sqrt55 (10 +2sqrt55)(10 -2sqrt55)
(sqrt6 +sqrt11 +sqrt5)(10 -2sqrt55)
= - --------------------------------------------------- =
100 -4*55
(sqrt6 +sqrt11 +sqrt5)(10-2sqrt55)
= - ------------------------------------------------------ =
100 -220
(sqrt6 +sqrt11 +sqrt5)(10-2sqrt55)
= - ---------------------------------------------------- =
- 120
(sqrt6 +sqrt11 +sqrt5)(10-2sqrt55)
= -----------------------------------------------------

1/(√6-√11+√5)=1 / [(√6+√5) -(√11)]
1 / [(√6+√5) -(√11)]=[1 / [(√6+√5) -(√11)]*[(√6+√5) +(√11)] / [(√6+√5)+(√11)]=
=(√6+√5+√11) / [(6+2√30+5) - 11]=
=(√6+√5+√11) / 2√30=
=(√6+√5+√11)*(2√30) / (2√30*2√30)=
