Problem 66 of 7
Rearrange exponential formula to isolate initial amount or rate factor: A=P(1+r)^t isolate r.
Using a hint is okay. It just tells the trainer to give you a little more review.

1. Divide by coefficient or initial amount.
2. Apply appropriate root or logarithm for the target.
3. State restrictions on bases, rates, and exponents.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Taking roots without accounting for exponent or sign constraints.
