( 6 √ 3 ) ² / 48 = ( 36 * 3 ) / 48 = 108 / 48 = 2,25
-------------------------------------------
72 / ( 2 √ 6 ) ² = 72 / ( 4 * 6 ) = 72 / 24 = 3
-------------------------------------------
90 / ( 9 √ 5 ) ² = 90 / ( 81 * 5 ) = 90 / 405 = 10 / 45 = 2 / 9
--------------------------------------------
( 2 √ 2 ) ² / 96 = ( 4 * 2 ) / 96 = 8 /96 = 1 / 12
--------------------------------------------
( √ 7 * √ 86 ) / √ 14 = √ ( 7 * 86 ) / √ 14 = √ 86 / √ 2 = √ 43
