log10(3) = 0.477121.... 10^0.477121.. = 3 (i.e. 10 raised to the exponent 0.477121...) If you are using log10, it's always easier to use multiples of 10 to explain so maybe this will help even more: log10(1000) = 3 10^3 = 1000 Hope this helps "ToM" <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > hi > > what is the opposite of a log? > > If you do lg10 of 3 in spss, it gives you a number. how can i take > this number and have as a solution the initial one (3) > > its easy but i cannot remeber!!!! ================================================================= Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =================================================================
