Find the Derivative - d/dx natural log of x^2+100

Problem

d(ln(x2+100))/d(x)

Solution

1. Identify the outer function as ƒ(u)=ln(u) and the inner function as u=x2+100

2. Apply the chain rule, which states that d(ln(u))/d(x)=1/u⋅d(u)/d(x)

3. Differentiate the inner function x2+100 with respect to x to get 2*x

4. Substitute the inner function and its derivative into the chain rule formula.

5. Simplify the resulting expression by multiplying the terms.

Final Answer

d(ln(x2+100))/d(x)=(2*x)/(x2+100)
