Ran in:
The format function will work once the symbolic answer has been converted to double precision using double, but you could use vpa instead (especially if the symbolic answer cannot be converted to double because it includes a symbolic variable.)
y = (200*sym(6151)^(1/2))/3 - sym(14200)/3
y = 
d = double(y)
d = 495.2207
format long
d
d =
4.952207476509858e+02
vpa(y, 6)
ans = 
495.221
