Question

the rationalising factor of
$2 + \sqrt{3}$
​

Answer 1

$2 - \sqrt{3}$

Step-by-step explanation:

1) Raitionalising factor of a + b√(c) = a - b√(c).

2) Raitionalising factor of a - b√(c) = a + b√(c).

3) Raitionalising factor of a + √(b) = a - √(b).

4) Raitionalising factor of a - √(b) = a + √(b).

5) Raitionalising factor of √a + √(b) = √a - √(b).

Raitionalising factor of 2 + √(3) = 2 - √(3).

Answer :

$2 - \sqrt{3}$
