SUMMARY
The statement that two irrational numbers \(x\) and \(y\) can be found such that \(x^y\) is rational is true. A well-known example is when both \(x\) and \(y\) are set to \(\sqrt{2}\). In this case, \(x^y = \sqrt{2}^{\sqrt{2}}\) may be either rational or irrational. If it is irrational, setting \(x = \sqrt{2}^{\sqrt{2}}\) and \(y = \sqrt{2}\) leads to \(x^y = 2\), which is rational. Another example includes \(\sqrt{2}^{\log_2 9} = 3\), further confirming the existence of such irrational pairs.
