Do 3/8 in your calculator. Then put -12 in front of the number. -12 and 0.375 = -12.375
It is: 12,000,000 or as 1.2*107 in scientific notation
It doesn't make much sense to calculate logarithms with pencil and paper - the calculations are too involved. Just multiply the two numbers, and calculate the logarithm on a scientific calculator. If you don't have one, use the Windows calculator (it has a mode for scientific calculator).
It is: 5.0*10^12
