Math Problem Statement

Given the function g(x) = ∛x, find its derivative.

Solution

The image shows a function g(x)=x3g(x) = \sqrt[3]{x} followed by some steps of simplification and differentiation.

Step-by-step explanation:

  1. Function definition: g(x)=x3g(x) = \sqrt[3]{x} This is the cube root of xx, which can also be written as: g(x)=x1/3g(x) = x^{1/3}

  2. Differentiation: To find g(x)g'(x), we use the power rule: ddx(xn)=nxn1\frac{d}{dx}(x^n) = n \cdot x^{n-1} Applying this to g(x)=x1/3g(x) = x^{1/3}: g(x)=13x23g'(x) = \frac{1}{3} x^{-\frac{2}{3}}

    This simplifies to: g(x)=13x23g'(x) = \frac{1}{3 \sqrt[3]{x^2}}

  1. How would you differentiate other radical functions like x\sqrt{x} or x4\sqrt[4]{x}?
  2. What is the significance of the power rule in calculus?
  3. Can you explain why the derivative of xnx^n changes when nn is a fraction?
  4. How would the derivative change if we were dealing with a higher root, like x5\sqrt[5]{x}?
  5. How do you interpret the derivative g(x)g'(x) in terms of rates of change?

Tip: When differentiating functions involving roots, always try to express the roots as fractional exponents for easier application of rules like the power rule!
