does it look like ? if so, it is the base.

remember what a logarithm is, logarithms are powers.

**Definition:**the logarithm of a number to a given base is the power to which the base must be raised to give the number.

that is, if then

example, since we have to raise the base 2 to the power 3 to get 8

now, is the power we have to raise to to get 9. so what number is that? - November 26th 2007, 06:42 PMDarkhrse99
I'm guessing it's 2, since we have to raise 2 to to equal 9.
