I feel like there is something wrong with this sentence.
I'm not a native speaker, but would agree that it sounds imprecise. To my understanding, that's a polynomial reduction of the time (O(n^2) to O(n): quadratic to linear) and not an exponential speed-up (O(2^n) to O(n): exponential to linear). 🤷 Colloquially, "exponentially" seems to be used synonymously to "tremendously" or similar.
Note that you can also have an exponential speed-up when going from O(n) (or O(n^2) or other polynomial complexities) to O(log n). Of course that didn't happen in this case.
Seem ok to me, both in grammar and what it's saying about the change. O(N²) to O(N) would be an exponential drop (2 down to 1, in fact).
An "exponential drop" would be a drop that follow an exponential curve, but this doesn't. What you mean is a "drop in the exponent", which however doesn't sound as nice.
There isn't. This is the colloquial use of "exponentially" which is very obvious from the context.
