Question

The value of (11 + √11) (11 – √11) is​

Answer 1

Step-by-step explanation:

$(11 + \sqrt{11} )(11 - \sqrt{11} ) \\ = {11}^{2} - { \sqrt{11} }^{2} \\ = 121 - 11 = 110$

Answer 2

(11+✓11)(11-✓11)

Here a property is being used

(a+b)(a-b)=a²-b²

Here a = 11

And B = ✓11

So,

(11+✓11)(11-✓11) = 11² - (✓11)²

=121 - 11

=110

THEREFORE 110 IS THE ANSWER ..
