Question

please tell me answer​

Answer 1

1/(2+√3)

= 1*(2-√3)/(2+√3)*(2-√3)

= (2-√3)/(2^2 - (√3)^2)

= (2 -√3)/(4-3)

= (2 - √3)

Answer 2

Answer:

2+√3/7

step by step explanation:

to rationalize denominator, we multiply both numerator and denominator with denominator

so, 1/2+√3 × 2+√3/2+√3

= 2+√3/(2+√3)(2+√3)

we know, (a+b)(a+b) = (a+b)²

= 2+√3/(2+√3)²

= 2+√3/4+3

= 2+√3/7

hence, denominator rationalized
