Find the Derivative - d/dx ( natural log of x)^3

Problem

d(ln(x))/d(x)

Solution

1. Identify the outer and inner functions to apply the chain rule. The outer function is u3 where u=ln(x)

2. Apply the power rule to the outer function by bringing the exponent to the front and subtracting one from the exponent.

3*(ln(x))2⋅d(ln(x))/d(x)

3. Differentiate the inner function ln(x) with respect to x

d(ln(x))/d(x)=1/x

4. Multiply the results together to find the final derivative.

3*(ln(x))2⋅1/x

5. Simplify the expression into a single fraction.

(3*(ln(x))2)/x

Final Answer

d(ln(x))/d(x)=(3*(ln(x))2)/x
