Most calculators have 2 different logs on them: log, which is base 10, and ln, which is base 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 needs a logarithm, he 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 as shown here:
Using this formula, find . Round your answer to the hundredth's place.

The logarithm's formula is:
Log.x(y) = h
if and only if
x to the power of h is y or x^y = h
So now if the base of the logarithm is 2 we can have something like this for example:
Log.2(x) = 3
Therefore:
2^3 = x
x = 8
Good luck.

if your trying to find the value with the base 2
then you use the change of base propoerty
its logb(x)=y
then y=log(x)/log(b)
divide the original log by the log of base
so it would be
y=log(x)/log(2)
in ur case

The formula and what you want to find are not showing up.
