A computer scientist might think of logarithm as follows: base a logarithm logan tells how many times the number n must be divided by a before reaching 1. For example log2 \&is 3 because 8/2/2/2 is 1 . If 1 is not reached exactly with whole divisions, the value of the logarithm has a fractional part that represents a last incomplete division. For example, log2 9is about 3.17 because 9/2/2/2 is 1.125, but a fourth division by 2 would take the value well below 1. Compute the following without a calculator. log464=log10100004log1000=log264=log775=
