The mass of a certain neutron star is 3.0 1030 kg (1.5 solar masses) and its radius is 7550 m. What is the acceleration of gravity at the surface of this condensed, burnedout star?

G*M*R^2,
where G is Newton's universal constant of gravity.
M = 3.0*10^30 kg
R = 7550 m
Use ^ signs before your exponents
