Q. Find the derivative of the following function.\newliney=log5(6x2+2x) y=\log _{5}\left(6 x^{2}+2 x\right) \newlineAnswer: y= y^{\prime}=
  1. Identify Function and Derivative Type: Identify the function and the type of derivative to be found.\newlineWe need to find the derivative of the function y=log5(6x2+2x)y = \log_5(6x^2 + 2x) with respect to xx. This is a logarithmic differentiation problem where the base of the logarithm is 55.
  2. Apply Chain Rule: Apply the chain rule for differentiation.\newlineThe 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. For the logarithmic function y=log5(u)y = \log_5(u), where u=6x2+2xu = 6x^2 + 2x, the derivative with respect to xx is (1/u)(du/dx)(1/u) \cdot (du/dx).
  3. Differentiate Inner Function: Differentiate the inner function u=6x2+2xu = 6x^2 + 2x with respect to xx. The derivative of uu with respect to xx is dudx=ddx(6x2)+ddx(2x)=12x+2\frac{du}{dx} = \frac{d}{dx}(6x^2) + \frac{d}{dx}(2x) = 12x + 2.
  4. Apply Change of Base Formula: Apply the change of base formula for logarithms. The change of base formula is logb(a)=logc(a)logc(b)\log_b(a) = \frac{\log_c(a)}{\log_c(b)}. We can use this to convert the base 55 logarithm to a natural logarithm: log5(u)=ln(u)ln(5)\log_5(u) = \frac{\ln(u)}{\ln(5)}.
  5. Combine Results for Derivative: Combine the results from Steps 22, 33, and 44 to find the derivative of yy. Using the chain rule and the change of base formula, the derivative of yy with respect to xx is y=1(6x2+2x)(12x+2)ln(5)y' = \frac{1}{(6x^2 + 2x)} \cdot \frac{(12x + 2)}{\ln(5)}.
  6. Simplify Derivative Expression: Simplify the expression for the derivative. \newliney=12x+2(6x2+2x)ln(5)y' = \frac{12x + 2}{(6x^2 + 2x) \cdot \ln(5)}.\newlineThis is the simplified form of the derivative.
