To start, we should choose a working definition of the value of , where is any real number. Although it is feasible to define the value as the limit of a sequence of rational powers that approach the irrational power whenever we encounter such a power, or as the least upper bound of a set of rational powers less than the given power, this type of definition is not amenable to differentiation. It is therefore preferable to use a functional definition, which is usually taken to be for … WebJan 4, 2024 · Proof of the power rule for derivatives (one of many ways to prove it).Need some math help?
