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

If you have a scientific calculator, there should be a key to input numbers in scientific notation. This key may be labeled "E" (uppercase E - the lowercase "e" means something different) or "Exp". In this case, press 1, EXP, 12 (meaning, 1 x 1012).

A scientific calculator typically has around 45 to 50 buttons, including numerical keys, mathematical function keys (such as addition, subtraction, multiplication, division), memory keys, trigonometric function keys, logarithmic function keys, and more. The exact number of buttons may vary slightly depending on the specific model and brand of the calculator.
