Given :

√23   + √3         √5     √5

√15  + √46          5        √10

3 + √115           √15       5

To find : value of determinant

Solution:

√23   + √3         √5     √5

√15  + √46          5        √10

3 + √115           √15       5

D = (√23   + √3  ) (5 * 5 - √15 √10)  -  √5 ( (√15  + √46)5 - ( 3 + √115) √10)  + √5 ( (√15  + √46)√15 -  ( 3 + √115)5)

= (√23   + √3  ) (25 - 5√6)  -  √5 (  5√15  + 5√46  -   3√10 - 5√46)  + √5 (  15  + √46√15 -  15 - 5√115 )

= 25 √23  - 5√138 + 25√3  - 15√2  - 25√3  + 15√2  + 5√138  - 25√23

= 0
