Q. For the following equation, find dydx \frac{d y}{d x} .\newliney=4x5+4x7 y=4 x^{5}+4 x-7 \newlineAnswer: dydx= \frac{d y}{d x}=
  1. Identify function: Identify the function to differentiate.\newlineWe are given the function y=4x5+4x7y=4x^{5}+4x-7 and we need to find its derivative with respect to xx, which is denoted as dydx\frac{dy}{dx}.
  2. Apply power rule: Apply the power rule to each term.\newlineThe power rule states that the derivative of xnx^n with respect to xx is nx(n1)n*x^{(n-1)}. We will apply this rule to each term in the function separately.
  3. Differentiate first term: Differentiate the first term 4x54x^{5}. Using the power rule, the derivative of 4x54x^{5} with respect to xx is 54x51=20x45\cdot 4x^{5-1} = 20x^{4}.
  4. Differentiate second term: Differentiate the second term 4x4x. The derivative of 4x4x with respect to xx is 44, since the power of xx is 11 and 1×4x11=4×1=41\times4x^{1-1} = 4\times1 = 4.
  5. Differentiate constant term: Differentiate the constant term 7-7. The derivative of a constant is 00, so the derivative of 7-7 with respect to xx is 00.
  6. Combine derivatives: Combine the derivatives of all terms to find dydx\frac{dy}{dx}.dydx=20x4+4+0\frac{dy}{dx} = 20x^{4} + 4 + 0 Simplify the expression by removing the 00.dydx=20x4+4\frac{dy}{dx} = 20x^{4} + 4
