SUMMARY
The discussion centers on finding the derivative of the function y=4^xlog_{9}(x) without using logarithms. The correct derivative is identified as 4^xln(4)log_{9}(x)+\frac{4^x}{xln(9)}. The participant realizes the necessity of applying the change of base formula to convert log base 9 into a more manageable form. This insight is crucial for solving similar problems in calculus.
