The correct Answer is:
To evaluate the limit \( \lim_{x \to 1} \frac{x - 1}{\log x} \), we can follow these steps: ### Step 1: Identify the form of the limit First, we need to substitute \( x = 1 \) into the expression: \[ \frac{1 - 1}{\log 1} = \frac{0}{0} \] This is an indeterminate form (0/0), which means we can apply L'Hôpital's Rule. ### Step 2: Apply L'Hôpital's Rule According to L'Hôpital's Rule, if we have an indeterminate form of type \( \frac{0}{0} \), we can differentiate the numerator and the denominator separately. - The derivative of the numerator \( x - 1 \) is: \[ \frac{d}{dx}(x - 1) = 1 \] - The derivative of the denominator \( \log x \) is: \[ \frac{d}{dx}(\log x) = \frac{1}{x} \] ### Step 3: Rewrite the limit Now we can rewrite the limit using the derivatives: \[ \lim_{x \to 1} \frac{x - 1}{\log x} = \lim_{x \to 1} \frac{1}{\frac{1}{x}} = \lim_{x \to 1} x \] ### Step 4: Evaluate the limit Now we can substitute \( x = 1 \) into the simplified expression: \[ \lim_{x \to 1} x = 1 \] ### Final Answer Thus, the value of the limit is: \[ \boxed{1} \]
