Q. Find the derivative of the following function.\newliney=ln(x68x5) y=\ln \left(x^{6}-8 x^{5}\right) \newlineAnswer: y= y^{\prime}=
  1. Identify Function Components: Identify the function and its components.\newlineWe have y=ln(x68x5)y = \ln(x^6 - 8x^5). The function inside the natural logarithm is u(x)=x68x5u(x) = x^6 - 8x^5.
  2. Find Inner Function Derivative: Find the derivative of the inner function u(x)=x68x5u(x) = x^6 - 8x^5. Using the power rule, we differentiate term by term. u(x)=ddx(x6)ddx(8x5)u'(x) = \frac{d}{dx}(x^6) - \frac{d}{dx}(8x^5) u(x)=6x540x4u'(x) = 6x^5 - 40x^4
  3. Apply Chain Rule: Apply the chain rule to differentiate y=ln(u(x))y = \ln(u(x)). The chain rule states that if y=ln(u(x))y = \ln(u(x)), then y=u(x)u(x)y' = \frac{u'(x)}{u(x)}. We already found u(x)u'(x) in Step 22, and u(x)u(x) is given by the inner function. y=6x540x4x68x5y' = \frac{6x^5 - 40x^4}{x^6 - 8x^5}
