Q. Given the function y=4x455 y=-\frac{4 \sqrt[5]{x^{4}}}{5} , find dydx \frac{d y}{d x} . Express your answer in radical form without using negative exponents, simplifying all fractions.\newlineAnswer: dydx= \frac{d y}{d x}=
  1. Given function: We are given the function y=45(x4)5y = -\frac{4\sqrt{5}(x^4)}{5}, and we need to find its derivative with respect to xx, denoted as dydx\frac{dy}{dx}. We will use the power rule for differentiation, which states that the derivative of xnx^n with respect to xx is nxn1n\cdot x^{n-1}.
  2. Rewrite function: First, let's rewrite the function to make it easier to differentiate. The function is y=45(x4)5y = -\frac{4\sqrt{5}(x^4)}{5}. We can pull out the constants and the radical to simplify the differentiation process.\newliney=45×5×x4y = -\frac{4}{5} \times \sqrt{5} \times x^4
  3. Apply power rule: Now, we apply the power rule to the x4x^4 term. The derivative of x4x^4 with respect to xx is 4x414\cdot x^{4-1} or 4x34\cdot x^3. \newlinedydx=4554x3\frac{dy}{dx} = -\frac{4}{5} \cdot \sqrt{5} \cdot 4 \cdot x^3
  4. Simplify constants: Next, we simplify the expression by multiplying the constants together. dydx=165×5×x3\frac{dy}{dx} = -\frac{16}{5} \times \sqrt{5} \times x^3
  5. Final expression: Finally, we express the answer in radical form without using negative exponents, simplifying all fractions. The expression is already in the correct form, so no further simplification is needed. dydx=1655x3\frac{dy}{dx} = -\frac{16\sqrt{5}}{5} \cdot x^3
