1.	The value of (root 11+root 2) (root 11- root 2)(A) 11(B) 2(C) 9(D) 13
Answer» Answer = 9 Step-by-step explanation: The EXPRESSION is in the FORM of an IDENTITY. (a+b) (a-b) = a²- b² Then, $(\sqrt{<klux>11</klux>} + \sqrt{2} ) \: ( \sqrt{11} - \sqrt{2} ) \:$ $= ( \sqrt{11} ^{2} ) - (\sqrt{2} ^{2} )$ = 11 - 2 = 9 Hope This Helps !!

Answer»

Answer = 9

Step-by-step explanation:

The EXPRESSION is in the FORM of an IDENTITY.

(a+b) (a-b) = a²- b²

Then,

$(\sqrt{<klux>11</klux>} + \sqrt{2} ) \: ( \sqrt{11} - \sqrt{2} ) \:$

$= ( \sqrt{11} ^{2} ) - (\sqrt{2} ^{2} )$

= 11 - 2

= 9

Hope This Helps !!
