%28sqrt%28-108%29%2B+sqrt%28-75%29%29 [factor the radicands into perfect squares]
%28sqrt%28-1%2A9%2A4%2A3%29%2Bsqrt+%28-1%2A25%2A3%29%29 [the square root of (-1)=i]
%283%2A2%2Ai+%28sqrt%283%29%29%2B5%2Ai+%28sqrt+%283%29%29%29
%286i%28sqrt%283%29%29%2B5i%28sqrt%283%29%29%29
.
%2811i%28sqrt%283%29%29%29 [treat the radicals as like-terms since both are the square root of 3; add the coefficients]
