    Easy Math Question

    Im trying to figure this out.

    20 = 10 log 10(S/N)
    Answer is 100.

    How can I do this on my calculator?

    20 = 10 log 10 (s/n); 1og 10 - meaning common log = log

    20/10 = log (s/n)

    2 = log (s/n)

    10^2 = 10^(log (s/n)); inverse log = 10^x (cancels) - here x = 2.

    100 = (s/n)

    Looks about right!
