Step-by-Step Solution

To solve the problem, follow these steps:

  • Step 1: Identify the expression to simplify, 1ln8 \frac{1}{\ln 8} .
  • Step 2: Apply the change of base formula:

Using the change of base formula, we have:
log8e=lneln8 \log_8 e = \frac{\ln e}{\ln 8} Since lne=1\ln e = 1, substituting gives:
log8e=1ln8 \log_8 e = \frac{1}{\ln 8}

Therefore, the expression 1ln8\frac{1}{\ln 8} can be rewritten as log8e\log_8 e.

Thus, the correct choice is log8e\log_8 e.

Answer

log8e \log_8e
