Hello there!
Using the given exponential function of y = 64(0.97)^x, we can tell that it is a decaying exponential function since the rate is less than 1.
The percent of decrease is 3% since 97% of the value is retained per x time.
As we have to solve for b, it means we have to isolate b
So first of all subtract 
from both sides
So we get
Now we need b , but its b^2 , so we can take square root on both sides.
taking square roots on both sides
Hence option B is correct
Answer:
it a or the first one or whatevr u wanna call it jsut #1
