Q. Find the derivative of the following function.\newliney=49x4 y=4^{9 x^{4}} \newlineAnswer: y= y^{\prime}=
  1. Identify Function & Differentiation Type: Identify the function and the type of differentiation required.\newlineWe are given the function y=49x4y=4^{9x^{4}} and we need to find its derivative with respect to xx. This is an example of a composite function where we have an exponential function with a base of 44 and an exponent that is itself a function of xx. To differentiate this, we will use the chain rule.
  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. In this case, the outer function is 4u4^u where u=9x4u=9x^{4}, and the inner function is u=9x4u=9x^{4}. We will first differentiate the outer function with respect to uu, and then multiply it by the derivative of the inner function with respect to xx.
  3. Differentiate Outer Function: Differentiate the outer function with respect to uu. The derivative of 4u4^u with respect to uu is (4uln(4))(4^u \cdot \ln(4)). This is because the derivative of aua^u with respect to uu is auln(a)a^u \cdot \ln(a), where ln\ln denotes the natural logarithm.
  4. Differentiate Inner Function: Differentiate the inner function with respect to xx. The derivative of 9x49x^{4} with respect to xx is 36x336x^{3}. This is because the derivative of xnx^n with respect to xx is nx(n1)n\cdot x^{(n-1)}.
  5. Combine Derivatives: Combine the derivatives using the chain rule.\newlineNow we multiply the derivative of the outer function by the derivative of the inner function to get the overall derivative of yy with respect to xx.\newliney=(49x4ln(4))36x3y' = (4^{9x^{4}} \cdot \ln(4)) \cdot 36x^{3}
  6. Simplify Expression: Simplify the expression if possible.\newlineIn this case, there is no further simplification that can be done without changing the form of the expression. So, the derivative of the function y=49x4y=4^{9x^{4}} with respect to xx is y=(49x4ln(4))36x3y' = (4^{9x^{4}} \cdot \ln(4)) \cdot 36x^{3}.
