Final answer:
The value of the exponential base (b) depends on the context of the problem and could be any of the given options.
Step-by-step explanation:
The value of the exponential base (b) depends on the context of the problem. It could be any of the given options: 0, 1, 2, or 3.
For example, if you are dealing with exponential growth or decay, the base (b) could be any positive number greater than 0. So in this case, options 1, 2, and 3 would be valid.
However, if you are working with logarithms, the base (b) is typically 10, so option 2 would be the correct answer.
