    Please answer the following questions:

    1. Find the domain of the function f(x) = ln(x - 7).

    2. Simplify: log 1000

    3. Write as a single logarithm (DO NOT find approximations): 2 log 4 + log x - log2.

    4. Expand and simplify: ln(e^x).

    5. Solve for x: log(x - 4) + log 2 = 1.
