Hi!
just use formula a+b * a-b = a^2 -b^2
For Eg √13+√11*√13-√11= 13-11
Both denominators will be equal.
Use (a+b)^2 =a^2+2ab+b^2 for numerator. Some numbers will cancel out... Whatever remains is the answer
Reason I didn't solve it completely is because if you try to solve it this once, you can easily ace your exams as you'll remember the method!
