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

Problem

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

Solution

1. Identify the constant multiple rule, which states that the derivative of a constant times a function is the constant times the derivative of that function.

2. Apply the constant multiple rule to move the 3 outside of the derivative.

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

3. Recall the derivative rule for the natural logarithm, which is d(ln(x))/d(x)=1/x

4. Substitute the derivative of ln(x) back into the expression.

3⋅1/x

5. Simplify the expression by multiplying the constant and the fraction.

3/x

Final Answer

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