Q. Given the function y=(2x1)4 y=(2 x-1)^{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=(2x1)4y=(2x-1)^{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.
  2. Derivative of Outer Function: The outer function is u4u^4 and the inner function is u=2x1u=2x-1. We first take the derivative of the outer function with respect to uu, which is 4u34u^3.
  3. Derivative of Inner Function: Next, we take the derivative of the inner function with respect to xx, which is the derivative of 2x12x-1. The derivative of 2x2x is 22, and the derivative of 1-1 is 00, so the derivative of the inner function is 22.
  4. Chain Rule Application: 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)=4u3×2(\frac{dy}{dx}) = 4u^3 \times 2.
  5. Substitute back uu: Substitute u=2x1u=2x-1 back into the expression to get the derivative in terms of xx. This gives us dydx=4(2x1)3×2\frac{dy}{dx} = 4(2x-1)^3 \times 2.
  6. Simplify Expression: Finally, we simplify the expression by multiplying the constants. This gives us (dydx=8(2x1)3)(\frac{dy}{dx} = 8(2x-1)^3).
