# Fixed Rate and Logarithm Change of Base Formula

For a fixed rate, a fixed principal amount, and a fixed compounding cycle, the return is an exponential function of time. Using the formula, A=P(1+r)^nt, let r=
n
10%, P=1 and n=1 and give the coordinates(t,A) for the points where t=0,1,2,3,4.

Using a calculator, find log 10000 where log means log to the base fo 10

Most calculators have 2 different logs on them, log, which is based 110, and in which is based e. In computer science, digital computers are based on the binary numbering system which means that there are only 2 numbers available to the computer, 0 and 1. When a computer scientist meeds a logarithm, he/she needs a log to base 2 which is not on any calculator. to find the log of a number to any base, we can use a conversion formula like this. logb a=log a
log b
Using this formula find log2 10000
