Question 1027042
1. Computing the amount of interest a bank account pays with compound interest


2. Exponential decay (e.g. given a substance with some half-life)


3. Determining the runtime of an algorithm or if the problem is in complexity class P, NP, EXP, etc. (this is a little more on the theoretical computer science side, but it has many real-world applications)


4. Exponentiation is used to compute many other functions that have real-world applications, such as all trig functions.
