Math Problem Statement

Differentiate the function y = 7e^x + 2ln(x)

Solution

To differentiate the function y=7ex+2ln(x)y = 7e^x + 2\ln(x), we will apply the rules for differentiation.

  1. Differentiate 7ex7e^x:

    • The derivative of exe^x is exe^x.
    • So, ddx(7ex)=7ex\frac{d}{dx}(7e^x) = 7e^x.
  2. Differentiate 2ln(x)2\ln(x):

    • The derivative of ln(x)\ln(x) is 1x\frac{1}{x}.
    • So, ddx(2ln(x))=21x=2x\frac{d}{dx}(2\ln(x)) = 2 \cdot \frac{1}{x} = \frac{2}{x}.

Now, combining both results:

y=7ex+2xy' = 7e^x + \frac{2}{x}

Final Answer:

y=7ex+2xy' = 7e^x + \frac{2}{x}

Tip: For logarithmic functions, remember that the derivative of ln(x)\ln(x) is 1x\frac{1}{x}, which is especially useful when combined with constants or more complex expressions.
