Is the answer to this problem correct? I'm not sure and I want to make sure I do well on the test.

Evaluate the following logarithms given log 4/log a = .321

The answer my teacher gave me was 0.963.

What is the reasoning behind the answer?

  • trig -

    What is the base of your logarithms? 10? Are you supposed to evaluate a ?

    I don't see how to get a = 0.963

  • trig -

    are you solving for a ?

    log 4/log a = .321
    log a = log 4/.321
    log a = 1.875576
    a = 10^1.875576
    = 75.089

    check
    log 4/log 75.089 = .321

    Is your question evaluate a given that log4/loga=0.321?

    if that's the case, then the answer is wrong.

  • trig -

    Yeah, it was to solve for A.
    I assumed it was to multiply by 3. Seeing as 4^3 = 64.

    log(sub a) 4 = .321
