1. Identify the logarithmic expression: 8\ln(x) - 5\ln(x).
2. Use the property of logarithms to combine: (8-5)\ln(x) = 3\ln(x) .
3. So, the answer is 3\ln(x).

Question: What is the value of f(x) when x = 10 in the logarithmic function f(x) = log x / f(x) = ln x?Answer: To find f(x) when x = 10, we substitute x = 10 into the function. Thus, f(10) = log 10 / f(10) = ln 10 = 1.
