----------- = ------------------------ = -------------------- = ------------------------- =
√(2+√3) √(2+√3)*√(2+√3) 2+√3 (2+√3)(2-√3)

7*(√(2+√3))*(2-√3)
= ----------------------------- = 7*(√(2+√3))*(2-√3) = 7*√(2+√3)*(2-√3)²) =
2²-√3²

=7*√((2²-√3²)*(2-√3)) =7*√((4-3) *(2+√3)) =7*√(2-√3))

( ⁴√7 -⁴√2)*(√7 +√2) ( ⁴√7 -⁴√2)*(√7 +√2) ( ⁴√7 -⁴√2)*(√7 +√2)
= ------------------------------- = ----------------------------- = ------------------------------
(√7 -√2 )(√7 +√2 ) 7-2 5

1 1*(√2-∛3) (√2-∛3) (√2-∛3)*(2²+2∛9+∛9²)
----------- = ------------------------ = ------------- = ------------------------------ =
√2+∛3 (√2+∛3)(√2-∛3) 2-∛9 (2-∛9)(2²+2∛9+∛9²)

(√2-∛3)*(4+2∛9+∛81) (√2-∛3)*(4+2∛9+∛81)
= ------------------------------- = ------------------------------- =- (√2-∛3)*(4+2∛9+∛81)
2³-∛9³ 8-9

((3+√2)+√3)*(8- 6√2) ((3+√2)+√3)*(8- 6√2) ((3+√2)+√3)*(8- 6√2)
= ---------------------------------- = ------------------------------ = ----------------------------------
(8+6√2)*(8-6√2) 8²-(6√2)² 64-72


   ((3+√2)+√3)*(8- 6√2)
= - -------------------------------
