Q. Find the derivative of the following function.y=ln(3x3)Answer: y′=
Identify Function Components: Identify the function and its components.The function y=ln(3x3) can be rewritten as y=ln(3)+ln(x3) by using the property of logarithms that ln(ab)=ln(a)+ln(b).
Differentiate Constant Term: Differentiate the constant term ln(3). The derivative of a constant is 0, so the derivative of ln(3) is 0.
Differentiate ln(x3): Differentiate the term ln(x3). Using the chain rule, the derivative of ln(u) with respect to x is u1⋅dxdu, where u=x3.
Find Derivative of u: Find the derivative of u=x3.The derivative of x3 with respect to x is 3x2.
Apply Chain Rule: Apply the chain rule to find the derivative of ln(x3). The derivative of ln(x3) is x31×3x2.
Simplify Derivative: Simplify the derivative.The derivative of ln(x3) simplifies to x33x2 which further simplifies to x3.
Combine Derivatives: Combine the derivatives of the constant term and the variable term.Since the derivative of ln(3) is 0, the derivative of the entire function y=ln(3x3) is just the derivative of ln(x3), which is x3.
