Q. Find the derivative of the following function.\newliney=log6(x5) y=\log _{6}\left(-x^{5}\right) \newlineAnswer: y= y^{\prime}=
  1. Identify Function and Derivative: Identify the function and the type of derivative to be found.\newlineWe are given the function y=log6(x5)y=\log_6(-x^5) and we need to find its derivative with respect to xx.
  2. Apply Chain Rule: Apply the chain rule for derivatives. The chain rule states that the derivative of a composite function is the derivative of the outer function evaluated at the inner function times the derivative of the inner function. In this case, the outer function is log6(u)\log_6(u) and the inner function is u=x5u=-x^5.
  3. Find Derivative of Outer Function: Find the derivative of the outer function.\newlineThe derivative of log6(u)\log_6(u) with respect to uu is 1uln(6)\frac{1}{u\ln(6)} because the derivative of logb(u)\log_b(u) is 1uln(b)\frac{1}{u\ln(b)}.
  4. Find Derivative of Inner Function: Find the derivative of the inner function.\newlineThe derivative of x5-x^5 with respect to xx is 5x4-5x^4.
  5. Apply Chain Rule with Derivatives: Apply the chain rule using the derivatives from steps 33 and 44. The derivative of yy with respect to xx is the derivative of the outer function evaluated at the inner function times the derivative of the inner function. So, y=1(x5ln(6))(5x4)y' = \frac{1}{(-x^5\ln(6))}\cdot(-5x^4).
  6. Simplify Expression: Simplify the expression.\newliney=5x4x5ln(6)y' = \frac{-5x^4}{-x^5\ln(6)}.\newlineWe can simplify this by canceling out an x4x^4 from the numerator and denominator.\newliney=5xln(6)y' = \frac{-5}{-x\ln(6)}.
  7. Cancel Negative Signs: Simplify further by canceling out the negative signs.\newliney=5xln(6)y' = \frac{5}{x\ln(6)}.
