1

Answer 2

Answer:

(2 +√3) (2-√3) = 1

Explanation:

To find:

The value of  (2 +√3) (2-√3)

Proof:

= (2 +√3) (2-√3)

= [ 2² - (√3)² ]                                              

Identity :   (a +b) (a-b) = a² -b²

Here,

• a = 2
• b = √3

= 4 - 3                                                   [   2²=4,     (√3)² = 3  ]

= 1

Hope you got that.

Thank You.
