Math Problem Statement

Find the derivative of the function f(x) = ln(5) + 0.6^x + ln(x).

Solution

We are asked to find the derivative of the function:

f(x)=ln(5)+0.6x+ln(x)f(x) = \ln(5) + 0.6^x + \ln(x)

Let’s break it down and apply the rules of differentiation:

  1. ln(5)\ln(5) is a constant, and the derivative of a constant is zero: ddx[ln(5)]=0\frac{d}{dx}[\ln(5)] = 0

  2. 0.6x0.6^x can be treated as an exponential function of the form axa^x. The derivative of axa^x with respect to xx is: ddx[ax]=axln(a)\frac{d}{dx}[a^x] = a^x \ln(a) So, ddx[0.6x]=0.6xln(0.6)\frac{d}{dx}[0.6^x] = 0.6^x \ln(0.6)

  3. ln(x)\ln(x) is a standard logarithmic function, and the derivative of ln(x)\ln(x) is: ddx[ln(x)]=1x\frac{d}{dx}[\ln(x)] = \frac{1}{x}

Now, combining all the derivatives, we get the total derivative of f(x)f(x): f(x)=0+0.6xln(0.6)+1xf'(x) = 0 + 0.6^x \ln(0.6) + \frac{1}{x}

Thus, the derivative of f(x)f(x) is: f(x)=0.6xln(0.6)+1xf'(x) = 0.6^x \ln(0.6) + \frac{1}{x}

Would you like further details or explanations on any part of this?

Here are five related questions to deepen your understanding:

  1. How do we differentiate exponential functions in general?
  2. What is the importance of the natural logarithm in calculus?
  3. Can we generalize the derivative of axa^x for any base aa?
  4. How would the derivative change if we had a function like f(x)=0.6x+ln(x)f(x) = 0.6x + \ln(x)?
  5. What is the difference between differentiating constant logarithms and variable logarithms?

Tip: Always remember that the derivative of a constant is zero, regardless of its complexity.
