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.
The value of (\log 50) can be calculated using logarithmic properties or a calculator. In base 10, (\log_{10} 50 \approx 1.699). For natural logarithms, (\ln 50 \approx 3.912). The exact value will depend on the logarithmic base you are using.
10^-1
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).
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 numerical value for "deca" is 10. It is a metric prefix used to denote a factor of ten in various measurements, such as decameter (10 meters) or decagram (10 grams).

The numeric value of log(x) is the power you have to raise 10 to in order to get 'x'.
