Question

simplify:
Radical 108a - Radical 27a

Answer 1

27 = 3*3*3
sqrt 27 = 3 sqrt3

108 = 3*3*3*2*2
sqrt 108 = 6 sqrt3

I don't know if your "a" is inside or outside the radical sign. You should use parentheses to indicate which is is. In any case, the difference between sqrt 108 and sqrt27 is 3 sqrt3. Put the 'a' or 'sqrt a' wherever it belongs, as a factor.
