Apply L'Hopital's rule. Note the numerator can be written: , and similarly the denominator can be written: . The derivative with respect to a of the numerator and the denominator are both: So the limit becomes:

a is a constant but what happens in the limit as it goes to zero?
Apply L'Hopital's rule. You can check your answer by plugging in random positive numbers for r and b and then putting in a small number for a and checking it in your calculator.
