Let me be straight, The question is...
2 / √13 - √11 .....
The rationalising factor is √13 + √11 ......
Hence the answer goes like.....
(2× √13 + √11) / 13 - 11 as (a+b)(a-b) = a² - b².
Well the final answer is....
(2√13 + 2√11)/ 2= √13 + √11
Hence you got your answer, feel free to hesitate & bit to ask any darn doubts. lol
