Proposition: General Powers of Positive Numbers

Let \(x\) be any real number and let \(a > 0 \) be a positive real number. Then the general power function \(a\to a^x\) is well-defined and equals the exponential function of general base \(a\), formally:


The following interactive figure demonstrates the general power in relation to different values of exponents \(x\in[-20,20]\).
