Q. For the following equation, find dydx \frac{d y}{d x} .\newliney=7x5+2x4 y=7 x^{5}+2 x^{4} \newlineAnswer: dydx= \frac{d y}{d x}=
  1. Identify function: Identify the function to differentiate.\newlineWe are given the function y=7x5+2x4y = 7x^{5} + 2x^{4} 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 for differentiation.\newlineThe power rule states that the derivative of xnx^n with respect to xx is nx(n1)n\cdot x^{(n-1)}. We will apply this rule to each term in the function separately.
  3. Differentiate first term: Differentiate the first term 7x57x^{5}. Using the power rule, the derivative of 7x57x^{5} with respect to xx is 5×7x51=35x45 \times 7x^{5-1} = 35x^{4}.
  4. Differentiate second term: Differentiate the second term 2x42x^{4}. Using the power rule, the derivative of 2x42x^{4} with respect to xx is 4×2x41=8x34 \times 2x^{4-1} = 8x^{3}.
  5. Combine derivatives: Combine the derivatives of both terms to find the overall derivative. dydx=35x4+8x3\frac{dy}{dx} = 35x^{4} + 8x^{3}.
