Acceleration Due to Gravity Problem **HELP**

1. The problem statement, all variables and given/known data
Titania, the largest moon of the planet Uranus, has 1/8 the radius of the earth and 1/1700 the mass of the earth...

What is the acceleration due to gravity at the surface of Titania? (m/s^2)

2. Relevant equations
g= GMe/Re^2

(Me) mass of planet

3. The attempt at a solution

well, i thought this was the right way of doing the problem, but i get a totally wrong answer and i am totally confussed on if this is the right equation for this problem or not.
