Problem

Let g(x)=(2x2+3x)5 (x2−1)1/3e3xg(x)=\dfrac{(2x^{2}+3x)^{5}\,(x^{2}-1)^{1/3}}{e^{3x}}. A student wishes to investigate the rate of change of gg with respect to xx. Respond to the prompts below, providing clear mathematical reasoning. (a) Describe—without performing any differentiation—the algebraic steps necessary to rewrite g(x)g(x) as a sum and difference of simpler terms that are easier to differentiate. Include a brief explanation of how each step reduces the complexity of the original expression. (b) Explain why differentiating ln⁡g(x)\ln g(x) can be computationally more efficient than differentiating g(x)g(x) directly for this function. (c) Identify all real values of xx for which each transformation you described in part (a) is valid, and justify your conclusions.
