Q. Find the derivative of the following function.\newliney=69x5 y=6^{-9 x^{5}} \newlineAnswer: y= y^{\prime}=
  1. Identify Function & Rule: Identify the function and the type of differentiation rule to apply.\newlineWe have the function y=69x5y = 6^{-9x^{5}}. To find the derivative, we need to apply the chain rule because the function is a composition of functions: an exponential function with a base other than 'e' and a power function.
  2. Rewrite Using Exponential: Rewrite the function using the natural exponential function for easier differentiation.\newlineWe can rewrite the function as y=eln(6)(9x5)y = e^{\ln(6) * (-9x^{5})} because ab=eln(a)ba^b = e^{\ln(a) * b} for any positive aa and real number bb.
  3. Apply Chain Rule: Differentiate the function using the chain rule.\newlineThe derivative of yy with respect to xx is y=ddx[e(ln(6)(9x5))]y' = \frac{d}{dx} [e^{(\ln(6) * (-9x^{5}))}].\newlineUsing the chain rule, we get y=e(ln(6)(9x5))ddx[ln(6)(9x5)]y' = e^{(\ln(6) * (-9x^{5}))} * \frac{d}{dx} [\ln(6) * (-9x^{5})].
  4. Differentiate Exponent: Differentiate the exponent ln(6)(9x5)\ln(6) \cdot (-9x^{5}). The derivative of ln(6)(9x5)\ln(6) \cdot (-9x^{5}) with respect to xx is ln(6)ddx[9x5]\ln(6) \cdot \frac{d}{dx} [-9x^{5}]. Since ln(6)\ln(6) is a constant, it remains as is, and the derivative of 9x5-9x^{5} is 45x4-45x^{4}. So, we have y=eln(6)(9x5)ln(6)(45x4)y' = e^{\ln(6) \cdot (-9x^{5})} \cdot \ln(6) \cdot (-45x^{4}).
  5. Simplify Derivative: Simplify the derivative.\newlineWe can now simplify the expression by substituting back the original base of the exponential:\newliney=69x5ln(6)(45x4)y' = 6^{-9x^{5}} \cdot \ln(6) \cdot (-45x^{4}).
  6. Check for Errors: Check for any mathematical errors. Review the differentiation steps to ensure that the chain rule was applied correctly and that the simplification steps are accurate.
