Q. Given the function y=4(x2+6x6)4 y=4\left(x^{2}+6 x-6\right)^{4} , find dydx \frac{d y}{d x} in any form.\newlineAnswer: dydx= \frac{d y}{d x}=
  1. Apply Chain Rule: To find the derivative of the function y=4(x2+6x6)4y = 4(x^2 + 6x - 6)^4 with respect to xx, we will use the chain rule. 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 u4u^4 (where u=x2+6x6u = x^2 + 6x - 6) and the inner function is x2+6x6x^2 + 6x - 6.
  2. Differentiate Outer Function: First, we differentiate the outer function u4u^4 with respect to uu. The derivative of u4u^4 is 4u34u^3.
  3. Differentiate Inner Function: Next, we differentiate the inner function x2+6x6x^2 + 6x - 6 with respect to xx. The derivative of x2x^2 is 2x2x, the derivative of 6x6x is 66, and the derivative of 6-6 is 00. So, the derivative of the inner function is 2x+62x + 6.
  4. Apply Chain Rule Again: Now, we apply the chain rule by multiplying the derivative of the outer function by the derivative of the inner function. This gives us: (dydx)=4u3×(2x+6)(\frac{dy}{dx}) = 4u^3 \times (2x + 6).
  5. Substitute Back Expression: We substitute back the expression for uu to get the derivative in terms of xx. So, dydx=4(x2+6x6)3(2x+6)\frac{dy}{dx} = 4(x^2 + 6x - 6)^3 \cdot (2x + 6).
  6. Simplify Final Derivative: Finally, we can simplify the expression by distributing the 44 into the expression (x2+6x6)3(x^2 + 6x - 6)^3. This gives us the final derivative: (dydx)=4×(2x+6)×(x2+6x6)3(\frac{dy}{dx}) = 4 \times (2x + 6) \times (x^2 + 6x - 6)^3.
