Determining units for a variable

Hi all,
I think I know the answer for the specific problem below, but I wonder if there is a more general process that could be evaluated using a program like MATLAB's Symbolic Math toolbox.
For example, in the equation
f(I)=a(1-exp(-b∙10^I))
let's say that I know that f(I) is in microvolts (uV), a is in microvolts (uV), and I is in log candela seconds per meter squared [log (cd s / m^2)]. If I don't know what unit b is in, is there any way to determine it "algebraically"?
Since f(I) and a are int he same units, then the expression in the exponent must be dimensionless, and so I take it that b must be equal to m^2/(cd∙s). But, assuming this is correct, how does one prove it?
Thank you in advance for your feedback.
