Question

(√3+1)(2-√3)/(2+√3)(2-√3)​

Answer 1

Step-by-step explanation:

$(\sqrt{3} + 1)(2 - \sqrt{3} )(2 + \sqrt{3} )(2 - \sqrt{3} )$

$(2 \sqrt{3} - 3 + 2 - \sqrt{3} )(2 {}^{2} - \sqrt{3 {}^{2} })$

$(2 \sqrt{3} - \sqrt{ 3} - 1)(4 - 3)$

$\sqrt{3 } - 1$

Answer 2

Answer:

(root 3 + 1 )(4 -3)(2 - root 3)

2 root 3 + 2- 3 - root 3

= root 3 - 1
