Math Problem Statement

Differentiate the function y = 2e^x + 7/x^(1/3)

Solution

The function provided in the image is:

y=2ex+7x3y = 2e^x + \frac{7}{\sqrt[3]{x}}

We need to differentiate this function with respect to xx.

Step-by-Step Solution

  1. Differentiate 2ex2e^x: The derivative of 2ex2e^x with respect to xx is: ddx(2ex)=2ex\frac{d}{dx}(2e^x) = 2e^x

  2. Differentiate 7x3\frac{7}{\sqrt[3]{x}}: Rewrite 7x3\frac{7}{\sqrt[3]{x}} as 7x137x^{-\frac{1}{3}}.

    Then, use the power rule to find the derivative of 7x137x^{-\frac{1}{3}}: ddx(7x13)=713x43=73x43\frac{d}{dx}\left(7x^{-\frac{1}{3}}\right) = 7 \cdot -\frac{1}{3}x^{-\frac{4}{3}} = -\frac{7}{3}x^{-\frac{4}{3}}

  3. Combine the results: Now, we can combine the derivatives: y=2ex73x43y' = 2e^x - \frac{7}{3}x^{-\frac{4}{3}}

Final Answer

y=2ex73x43y' = 2e^x - \frac{7}{3x^{\frac{4}{3}}}

Here are five related questions to explore:

  1. How would you differentiate a function with a variable in both the numerator and denominator?
  2. What are the steps to differentiate composite functions like ex2e^{x^2}?
  3. How can you use implicit differentiation on functions not explicitly solved for yy?
  4. What techniques would be useful for differentiating logarithmic functions?
  5. How does the power rule apply when the exponent is negative or a fraction?

Tip: Remember, for fractional exponents, rewriting the function in terms of powers makes differentiation more straightforward.
