1 month ago - Early in the 17th century, the first form of our modern exponential notation was introduced by René Descartes in his text titled La Géométrie; there, the notation is introduced in Book I. I designate ... aa, or a2 in multiplying a by itself; and a3 in multiplying it once more again by a, and thus to infinity. ... Some mathematicians (such as Descartes) used exponents only for powers greater than two, preferring to represent squares as repeated multiplication.

r/learnmath on Reddit: What is the definition of an exponent?
June 28, 2022 -
Hello everyone! I was wondering what the formal definition of an exponent is. I’ve made it through calc 2 and up until now the only detention I’ve received is either an is a multiplied by itself n times or given am/n would be the nth root of am, for example sqrt(a) is a1/2. However I was wondering if there is a more formal definition. For example, 2pi can be computed, but wouldn’t work with the above definitions, as you can’t multiply 2 pi times and pi is an irrational number.
Any insight on this would be much appreciated!

For natural a, we define ba as ∏(b) a times, but for any real a and positive real b, we define ba = exp(a*ln(b)).

As other commenters have made clear, there are several different answers to this question. No matter which approach you choose, there are theorems that need to be proved in order for the definition to be coherent. For example, if you take u/Crafty_Potatoes 's definition, you have to prove that this definition of exponentiation preserves the properties we like, for example, aman = am+n. This kind of thing will be true of any definition you adopt. Similarly, you should definitely believe u/thecooIestperson about the definition of exp, but again, you will want to prove that, essentially, exp(x) = er for r rational and e is a single well-defined constant. If you adopt u/bluesam3 's definition, your soul will be unsatisfied unless you prove that it implies u/thecooIestperson 's series identity. Vice versa, too. Even u/ConservatoryCanine 's definition incurs a theoretical debt: to prove that the exponential identities are true, and that the definition is coherent (as they acknowledge in their comment).
