Math Problem Statement

Consider the following.

y = ln(x5),    (1, 0)

(a)

Find y ′.

Solution

To find yy' (the derivative of yy with respect to xx), given the function y=ln(x5)y = \ln(x^5) and the point (1,0)(1, 0), we'll proceed as follows:

Step 1: Simplify the logarithmic expression

We can use the logarithm power rule: y=ln(x5)=5ln(x)y = \ln(x^5) = 5\ln(x)

Step 2: Differentiate the function

Now, differentiate y=5ln(x)y = 5\ln(x) with respect to xx: [ y' = \frac{d}{dx}[5\ln(x)] = 5 \cdot \frac{d}{dx}[\ln(x)] ] y=51x=5xy' = 5 \cdot \frac{1}{x} = \frac{5}{x}

Step 3: Evaluate the derivative at the given point

We are asked to find the derivative at the point (1,0)(1, 0). Since x=1x = 1 at this point: y=51=5y' = \frac{5}{1} = 5

So, the derivative yy' at the point (1,0)(1, 0) is: 5\boxed{5}

Tip: When differentiating functions involving logarithms, it's often helpful to simplify the logarithmic expression using the logarithm rules before differentiating. This can make the derivative much easier to compute.
