  1 /  [ sqrt 36 - sqrt 27 ] - 1 / [ sqrt 27 - sqrt 18 ] +  1 / [ sqrt 18 - sqrt 9]

 

1/ [ 6 - sqrt 27 ]  - 1 / [ sqrt 27 - sqrt 18] + 1 / [sqrt18  - 3]

 

[ 6 + sqrt 27 ] / [ 36 - 27]   - [ sqrt 27 + sqrt 18]  / [ 27 - 18]  + [sqrt 18 + 3 ] / [18 - 9]

 

[ 6 +sqrt 27 ] / 9   -  [ sqrt 27 + sqrt 18 ] / 9  +  [ sqrt 18   + 3  ]  / 9  

 

[  6 + 3 ]  / 9  =
