Question

pls answer this one​

Answer 1

Answer:

0

Step-by-step explanation:

Rationalising the denomenators of each term

1 / 2+√3 = 1(2-√3) / (2+√3)(2-√3) = 2-√3

2 / √5-√3 = 2(√5+√3) / (√5 -√3)(√5+√3) = 2(√5+√3) / 2 = √5+√3

1 / 2-√5 = (2+√5) / (2-√5)(2+√5) = -2-√5

(2-√3) +(√5+√3) +(-2-√5) = 0

hope that it is correct
