SUMMARY
The discussion focuses on proving that the limit of the sequence \((a_n)^{b_n}\) converges to \(a^b\) as \(n\) approaches infinity, given that \(a_n\) converges to \(a\) and \(b_n\) converges to \(b\). The key approach involves using the hint that \((a_n)^{b_n} = e^{b_n \log(a_n)}\) and applying the continuity of the exponential and logarithmic functions to move the limits inside the function. The goal is to establish that \((a_n)^{b_n} \rightarrow a^b\) as \(n \rightarrow \infty\).
