Evaluate expression when two complex numbers are given

Full solution

Q. Let

y=x^{2} \ln (x)

.

\newline

\frac{d y}{d x}=

Identify Product Rule: We need to use the product rule because $y$ is the product of two functions of $x$ , which are $x^2$ and $\ln(x)$ .
Product rule: $(d/dx)[u*v] = u*(dv/dx) + v*(du/dx)$
Let $u = x^2$ and $v = \ln(x)$ .
Differentiate $u$ : Differentiate $u$ with respect to $x$ . $\frac{du}{dx} = \frac{d}{dx}(x^2) = 2x.$
Differentiate $v$ : Differentiate $v$ with respect to $x$ . $\frac{dv}{dx} = \frac{d}{dx}(\ln(x)) = \frac{1}{x}.$
Apply Product Rule Formula: Now plug the derivatives and the original functions into the product rule formula. $\newline$ $(\frac{dy}{dx}) = x^{2}*(\frac{1}{x}) + \ln(x)*(2x)$ .
Simplify Expression: Simplify the expression. $\newline$ $(\frac{dy}{dx}) = x + 2x\ln(x)$ . $\newline$ Oops, made a mistake here, should have been $\frac{x^2}{x}$ which is $x$ , not just $x$ .
