The answer
It is a complexity where the processing time doubles for every single additional element added to the input data.

What is O(2^N) Exponential Time?

Quadratic time grows predictably. N=50 in O(N^2) is 2500 operations. N=50 in O(2^N) is over 1 Quadrillion operations, making it physically impossible to compute.
It is almost always caused by recursive functions that make two recursive calls to themselves, creating an exponentially growing tree of execution.
Yes, for generating combinations, permutations, or Power Sets, generating the data mathematically requires exponential operations because there are exponentially many outputs.
