5%2F%28sqrt%283%29%2Bsqrt%285%29%29
.
To "rationalize" means to get rid of those square root signs in the denominator.
.
Start by multiplying numerator and denominator by:
%28sqrt%283%29-sqrt%285%29%29%2F%28sqrt%283%29-sqrt%285%29%29
.
So we have:
5%2F%28sqrt%283%29%2Bsqrt%285%29%29* %28sqrt%283%29-sqrt%285%29%29%2F%28sqrt%283%29-sqrt%285%29%29
.
For the numerator we have: 5%28sqrt%283%29-sqrt%285%29%29
For the denominator we have: 3-5 = 2
