Identify Function: We need to find the derivative of the function h(x)=x2ln(x). To do this, we will use the quotient rule for derivatives, which states that if we have a function that is the quotient of two functions, v(x)u(x), then its derivative is given by (v(x))2v(x)u′(x)−u(x)v′(x). Here, u(x)=ln(x) and v(x)=x2.
Derivative of ln(x): First, we find the derivative of u(x)=ln(x). The derivative of ln(x) with respect to x is x1.u′(x)=x1
Derivative of x2: Next, we find the derivative of v(x)=x2. The derivative of x2 with respect to x is 2x.v′(x)=2x
Apply Quotient Rule: Now we apply the quotient rule. We have:h′(x)=(v(x))2v(x)u′(x)−u(x)v′(x)Substituting u(x), u′(x), v(x), and v′(x) into the formula, we get:h′(x)=(x2)2x2⋅(x1)−ln(x)⋅2x
Simplify Expression: Simplify the expression by performing the multiplication and division: h′(x)=x4x−2x⋅ln(x)
Factor Out x: We can further simplify by factoring out an x from the numerator: h′(x)=x4x(1−2ln(x))
Cancel x: Finally, we can cancel one x from the numerator and denominator:h′(x)=x31−2ln(x)This is the simplified form of the derivative of h(x).
