    How to solve a log problem???

    If I have this:

    log(x) = -3.87

    and I want to find x, do I assume that this a natural logarithm, or a base 10?

    In other words, does x = 10^-3.87 or x = e^(-3.87) ????

    Thanks!

    I would assume base 10

    \ln(x) should be written for base e.

    Although you can never be 100% sure, ask your teacher
