Good caluclation.

By doing LCM b/w root3 and 1/root3 also we can get that easily.

How to calculate LCM? 
Amit said: (Feb 20, 2015)  
It is (ab)square = (a square+b square2ab). 
Joslin said: (Apr 5, 2015)  
Taking LCM. = (sqrt3 1/sqrt3)^2. = ( (31)/sqrt3)^2. = (2/sqrt3)^2. = 4/3.

Any one please explain this sum? 
Simi said: (Mar 24, 2016)  
Use the formula: (ab)^2 = a^2 + b^2  2(a*b).

= sqrt3/1  1/sqrt3. = sqrt9  1/sqrt3. = (3  1/sqrt3)^2. We know that, (a/b)^2 = a^2/b^2. so, = (2^2)/(sqrt3^2). = 4/sqrt9. = 4/3.

In this sum, why don't we use BODMAS condition?
