Answer 1

Hey friend, ☺ here is ur answer ___________________________

$(5 + \sqrt{11} )(5 - \sqrt{11} ) \\ putting \: formula \: (x - y) (x + y)= {x}^{2} - {y}^{2} \\ = {5}^{2} - { \sqrt{11} }^{2} \\ = 25 - 11 \\ = 14$




Hope this helps u...

Answer 2

Heya !

••••• ••••• ••••• Answer ••••• ••••• •••••

( 5 + √11 ) ( 5 - √11 )

[solve using → ( a - b ) ( a + b ) = a raised to the power 2 - b raised to the power 2]

= 5 raised to the power 2 - √11 raised to the power 2 or(5^2 - √11^2)

=25 - 11

= 14
Its Simple !
