    Following, I had the same issue and even after looking at youtube videos, I don't understand what I'm doing wrong.

    This is likely an error in the book and you are using the function correctly.  If not, I, too, am going crazy.

    I cam across this recently in my studies, but it didn't cause me to flinch. I'm not sure what you are doing wrong, make sure you are closing parentheses correctly (some calculators don't follow the order of operations correctly). If all else fails, check your work on Google.

    log(8) = 0.903

    10 * log(8) = 9.03

    73 + 10 * log(8) = 82.03

    the answer is 82 dB

    I put it in the calculator wrong. I kept typing 10Log then (8) which was giving me an error. It is actually supposed to be typed 

    Log8 then multiply it by 10.

    Thank you Peter!

    The calculator sucks. I'm used to a Hewlett Packard 32 which I've been using for over thirty years. When you are used to the RPN, this drugstore calculator seems like Fisher Price.
