The solutions to this equation are not unique. Based on the requirements given there is an entire solution space for each possibility. For example 1.024E4*2^-10 = 10 but that is not a valid answer. Basically there is a degree of freedom issue here.

agree,solutions is way way more than one.

b=0. a=x.

Brute-force on b, while looking for solutions with a restricted to the interval [-1,1] works. And I agree there is more than one solution. The author should specify what is the interval for valid solutions or accept more than one valid answer (which is easy to verify).
