C) $\frac { - \ln x - 1 } { 49 x ^ { 7 } }$
D) $\frac { - 6 \ln x - 1 } { 36 x ^ { 6 } }$

Question

Quizplus · Accepted Answer

The correct answer is obtained by integrating the given function $\int \frac{\ln x}{x^8} dx$. The integration process involves using integration by parts or recognizing it as a standard form, leading to the result $\frac{-7\ln x - 1}{49x^7}$, which matches option B.
