The numerical value of the natural log of 10 is 2.30258509299045684. The complete equation can be found on mathworld by wolfram. All further workings are too complex to explain in a small space.
To make a natural log a log with the base of 10, you take ten to the power of you natural log. Ex: ln15=log10ln15=log510.5640138 I'm sorry if you don't have a calculator that can do this, but this will work.
10^-1
1/10
To simplify (\log(xy)), you can use the logarithmic property that states (\log(xy) = \log(x) + \log(y)). Given (x = 12) and (y = 20), you can calculate (\log(12) + \log(20)). If you need a numerical value, you can evaluate it using a calculator, resulting in approximately (1.0792 + 1.3010 = 2.3802) (using base 10 logarithm).
1.6 x 10^-19.......=........0.00000000000000000016

Very simple: it is 1.6989700043 to be exact. You can test this because log50 means we assume the natural log (base 10), if you test 10 to the exponent of 1.6989700043 you should render 50 as your result :D
The numeric value of log(x) is the power you have to raise 10 to in order to get 'x'.
