Question

Q 1/√4-√3 =?
(a) (2+v3)
(b) 1
(c)(2-√3)​

Answer 1

Answer is (A) (2+ root3)
STEP BY STEP EXPLANATION
I/root4 - root 3
Rationalising the denominator
1 (root4 + root3) / root4 - root3 ) ( root4 + root3 )
We know that (a-b)(a+b)= a^2-b^2
So, this becomes
Root4 + root 3 / (root4)^2 - (root3)^2
= root4 + root3 / 4-3
= root4 + root3
= 2 + root3

Answer 2

$2 + \sqrt{3}$
