MATLAB: Solve 2 equations(type: power) and 2 unknowns

equationsolve

Hi,
I have 2 equations wich are similar to each other with different constants. There are 2 unknowns that I wanna find. But my answers are so confusing.
These unknows are actually constants that I am looking for the magnitudes by the help of experimental data.
Here is my code:
syms c g
sol=solve([5.8723e-10 == c/(1-0)^g , 5.213e-10 == c/(1-0.1)^g],[c,g]);
format shortEng
sol.c
sol.g
and here is my results:
ans =
 
2839670036209195/4835703278458516698824704
 
 
ans =
 
-(log(2520852119060425) - 82*log(2) + log(4835703278458516698824704/2839670036209195))/log(9/10)
It should show me 2 real numbers.
Many thanks in advance.

The format function does not affect how symbolic expressions are displayed. Call double or vpa on the elements of the sol struct array.
