- If α and β are algebraic numbers (with α≠0 and \(\log \alpha\) any non-zero logarithm of α), and if β is not a rational number, then any value of \(\alpha^{\beta} = \exp\{\beta \log \alpha\}\) is a transcendental number. ===Comments=== * The values of \(\alpha\) and \(\beta\) are not restricted to real numbers; all complex numbers are allowed. * In general, \(\alpha^{\beta} = \exp\{\beta \log \alpha\}\) is multivalued, where "log" stands for the complex logarithm. This accounts for the phrase "any value of" in the theorem's statement. * An equivalent formulation of the theorem is the following: if \(\alpha\) and \(\gamma\) are nonzero algebraic numbers, and we take any non-zero logarithm of α, then \((\log \gamma)/(\log \alpha)\) is either rational or transcendental. * If the restriction that \(\beta\) be algebraic is removed, the statement does not remain true in general (choose \(\alpha=3\) and \(\beta=\log 2/\log 3\), which is transcendental, then \(\alpha^{\beta}=2\) is algebraic). A characterization of the values for α and β which yield a transcendental αβ is not known.
